Watch your behavior and actions:

 Dear brother, the Prophet, peace be upon him, said: 

((You are a corner among the many corners of Islam, so don't let Islam be attacked from your side!))

 Yes my brother, each one of you is a corner in Islam, so don't let Islam been attacked from your side. Thughrah (a corner in this context) has different meanings: it could be the vulnerable area of the boundaries, the blunt in something and the hole in the dress. Hence, don't be the reason behind offending Islam and Muslims. People do not love Islam as a divine religion which accords with reasoning and Fitrah, as much as they do when they see it applicable in daily life and manifested in Muslim's behavior.

 Dear brother, people learn by watching more than listening, so keep in mind that Islam was spread in East and South Asia and in West and North Africa, because of the good conducts and straight behavior of early Muslim merchants who set good examples to people of those countries by being upright, honest and trustworthy. In fact, people abhor Islam when they see a Muslim, who is entirely devoted to his acts of worship (Salah, Sawm and Du'a), does harm to people in selling, buying, lending money and in rendering his debts.

 Dear brother, when you do harm, Allah forbid, to other people, actually your misbehavior affects negatively not only you as a Muslim,, but also Islam and Muslims. People usually give cold shoulder to Kuffar and deviated people when they offend other people, doing harm to them and seduce them. However, they raise hell against, threaten and denounce Muslims and even Islam for a simple mistake a Muslim does even though it might be unintentionally done, La Hawla Wala Quwwata Illa Billah (There is no Might, nor Strength except through Allah).

 Dear brother, Muslim's behavior and actions are in spotted and every move or still are counted against him. Let alone, people are keen on keeping a close eye on his behavior and actions and criticizing them. When a young man is used to be morally deviated and to commit sins, since this is the social environment he has been raised in, people forgive him, make excuses for his misbehavior and take into consideration the circumstances he is under and the needs which he has to satisfy. Nevertheless, when his heart finds its way to Islam and he intends to attain safety, purity and chastity, his behavior becomes the subject of criticism, his actions are counted against him and the simple mistake he does will be turned against him and against his religion. Also, people keep saying, "Is this how the Muslim and the believer behave?" La Hawla Wala Quwwata Illa Billah.

 Dear brother, don't be surprised (if people's reaction is harsh on the Muslim's unintentional misbehavior). The believer is supposed to be pious and straight, as he represents not only himself or his clan, but also Allah's religion that which He has chosen for mankind and his Prophet, peace be upon him, who is an exalted exemplar of good conducts.

 Would you like to offend your Islam and your Prophet, peace be up him and his Companions? If you wouldn't, then always recall the saying of the Prophet, peace be upon him:

((You are a corner among the many corners of Islam, so don't let Islam be attacked from your side!))

Umar is a good example for us:

 Our master Umar Ibn Al-Khattab used to gather his family members and address them whenever he enacted a law: 

((  ((People will now look at you just as bird looks at meat. If you come to grab it, they will grab with you, and if you refrain, they refrain. If I issue an order prohibiting something on people, then you must be the first to refrain from it. By Allah, if any one of you is brought to me, having done what I have ordered people to refrain, I will double his punishment because of his relation to me. Until one of you will say: how I wish our father has not assumed the leadership of the Muslim state, so that we would be like any other person. )) ))

 Applying Islam first to himself and those who are closer to him, was the method Umar followed in making people love Islam. Umar, may Allah be pleased with him used to say:

((  ((How can I care about Muslims if I don't eat the same food they eat.)) ))

 During the year of the ashes, a camel was slaughtered, and its meat was distributed among the people. The people who were in charge of the slaughtering saved the best parts of the camel for Umar Ibn Al-Khattab; those parts included meat from the hump of the camel and from its liver. When the meat was presented to him, Umar asked: "Where did this meat come from?" Someone replied, "O leader of the believers, from the camel that we slaughtered today." Umar replied, "Wonderful! Wonderful! But what a vile leader I would be if I ate the best part of the camel and left the people to eat its bones. Lift up this tray, and bring me some other food." Some bread and oil were procured for him, and he began to break the bread with his hand and dip it in oil.
 One day he saw a fat camel for sale in the market, and he asked, "Whose is this camel?" The people there answered him, "It is Abdullah bin Umar's" Upon hearing that, he got angry saying, "It is Abdullah bin Umar's! Alas, it is yours O son of the leader of the believers." He asked people to get Abdullah to him. When Abdullah was before his father, Umar said, "Where did you get this camel from, O Abdullah?" Abdullah replied, "It was a very thin camel which I bought it with my own money. I put it in the government grazing ground where it became healthy, and so I could make money from it like other people do." Then Umar said to his son, "People might say, 'let this camel eat more as it belongs to the Khalifa's son, let it drink more as it belongs to the Khalifah's son', and so it gets fat brining you more benefits, O You son of the Khalifah." Umar addressed his son saying, "O Abdullah bin Umar, sell the camel and take only your capital money and give the rest to the Muslims' treasury (exchequer)."

 When Umar visited As-Sham, they brought him different kinds of food, and instead of eating and enjoying the food he wept and said:

((  ((All this food is for us, while our brother died poor and never ate enough of barley bread.)) ))

 May Allah be pleased with you our master Umar, for you were the most merciful of this Ummah to this Ummah (the nation of Islam). I would like you dear believer brother to keep recalling the saying of the Prophet, peace be upon him:

((You are a corner among the many corners of Islam, so don't let Islam be attacked from your side!))

 When a Muslim treats other people badly, he actually offends himself and his religion (Islam). Not to mention, he might unintentionally distort Islam in the sight of non-Muslims. Souls were molded to love the benefactor and hate the hurtful, and both (hatred and love) are contagious like diseases. The Prophet, peace be upon him, addressed Salman Al Farisi: Salman narrated, the Prophet, peace be upon him, said to me:

((You will leave your faith if you hate me." (Salman Farsi replied), "How can we hate you? May my mother and father be sacrificed for you O Rasulullah (sallallahu alaihi wa sallam). Through you, Allah guided us to the right way, how can I not love you?" The Messenger of Allah replied, "If you don't love the Arabs, you don't love me.")) Abu 'Isa said that this Hadith is Hasan and Ghareeb, and is only narrated by Abi Badr Shuja' Ibn Al-Waleed and Muhammad Ibn Islam'eel was heard saying: Abu Zabian said that Salman died before Ali.

[At-Tirmizi and Ahmad]

 Dear brother, call yourselves to account before you are called to do so, weigh your deeds before they are weighed and keep connected with Allah in order to be pleased. You should know that the Angel of Death has been reaching sh3er and will reach us soon, so pay heed. The clever one is he who upbraids himself and works for what comes after death; and the weak one is he who follows his desires and lives on wishful thinking, and praise be to Allah, the Lord of the Worlds.

Second Khutbah:

 Praise be to Allah, the Lord of the Worlds, and I testify that there is no god but Allah Alone, the Guardian of the pious, and I testify that our Master Muhammad is his slave and Messenger, who is on an exalted standard of character.

Supplication:

 We beseech you Allah to show us the way of rightness, together with those to whom You have showed it; and give us good health, together with those whom You have healed; and be our Protector, together with those for whom You have become their Protector; and bless us in what You have bestowed on us and save us from the afflictions that You have decreed, for You rule with justice and You are never judged. 

 O Allah, increase us [in Your Blessings] and do not decrease us, honor us and do not humiliate us, give us [from Your Gifts] and do not deprive us, be in favor of us and not against us, and make us satisfied and be satisfied with us.
 O Allah, dignify us by Your generosity and don't make us lose our dignity in trials, turning to the worst among your creations, praising those who give us and dispraising those who don't, for You are the One who bestows and in Your hands only the treasures of heaven and earth. O Allah, please lead us to the good deeds, for no one leads to them but You and please save us from the bad deeds, for no one saves us from them but You.
