Al-Fitrah and man's reason are the means for his perception, the paths to seek knowledge and they complete one another for the purpose of knowing Al-Haqq (the truth) and Al-Batil (falsehood), the good and evil and the right and wrong. The mind analyses, puts facts together, deduces, seeks information, believes, adopts thoughts, doubts, evaluates and rejects. These are mental proceedings done by the mind, whereas the soul gets comfortable, feels pain, worries, fears and loves, or it is motivated, and these are the psychological activities of man. Hence, both the mind and the Fitrah are guides, they work together and they complete each other, better yet they are man's means to know Al-Haqq and to disclose Al-Batil. Nevertheless, the mind is unable to oblige man to abide by what is right, for there are many highly educated people who are smokers, and this means that having information is not enough alone, and so man should have the strong will to abide by the right piece of information. As for Fitrah, it is subject of distortion, and it might be effaced because of the environment, so in this case what is the thing that is constant for Muslim? It is the Divine Revelation which:

﴾Falsehood cannot come to it from before it or behind it (it is) sent down by the All-Wise, Worthy of all praise (Allah)﴿

[Fussilat, 42]

 This Revelation is the unquestionable Haqq, the reference and the absolute value (of measuring). Accordingly, whatever the mind figures, and it is in harmony with the Quran and the Sunnah, is right, and whatever the mind reaches, and it contradicts the Quran and the Sunnah, is wrong and should not be accepted, because the Revelation put forth the absolute truth. Moreover, when Al-Fitrah is effaced, it might get comfortable upon doing something that opposes religion, and this is not out of sound Fitrah, but it is the outcome of distorted and changed Fitrah. In fact, as long as we abide by the Quran and Sunnah, we shall never be misguided.

 The mind is our means to get acquainted with Allah through pondering over His Creations, whereas Al-Fitrah is our means to follow the Path of Allah for it is our inner detector which gets comfortable upon obeying Allah and becomes disturbed upon disobeying Him. Allah the Almighty is the absolute Perfection, so is His religion. Allah says:

﴾This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion.﴿

[Al-Ma'idah', 3]

 Completion is in quantity, whereas perfection is in quality. In other words, the numbers of issues dealt by religion are complete, they cover everything, and they are perfect in the quality of tackling them. This religion is the religion of Allah, and when Allah tells us that no falsehood shall come to it from before it or behind it, and that it is the Revelation from Allah the Almighty, He means that we are not allowed to add to it, lest we are divided into cults and sects, which will conflict and compete with one another, their enmity among themselves will become very great, and in its turn it will be the reason of Muslims' disunity and shattering. Also, we should not omit anything from religion, lest we fall in weakness, backwardness and destruction. It is reported in the relic:

((O Ibn Umar, your religion, your religion is your flesh and blood. Take it from the pious ones, and do not take it from those who deviated.))

[Mentioned by Ibn Al-Jawzi in Al-'Ilal Al-Mutanahiyah]

 Ibn Sireen reported:

((This knowledge contains the rules of the religion, so look thoroughly into the person from whom you acquire the knowledge of your religion.))

[Mentioned by Muslim in his introduction]

 Religion is a fateful matter, and by Allah in whose hand Muhammad's PBUH soul is, there is no abode after the worldly life but Paradise or Hellfire. To clarify the seriousness of the matter of religion, allow me to give you an example from reality: if you go to the wellspring of a river, you will see that the water is clear, but if you check it on the river mouth after it receives all the side brooks and drains, you will find that its water is black and muddy. Similarly, this religion is great, so we should take it from its pure sources, and this is the precise meaning of rejuvenating the religion, but some people might assume that rejuvenating the religions means to come up with a new religion, which is totally wrong. Rejuvenating the religion has one precise meaning which is to remove the matters that do not belong to it.

 When some groups deviate from the essence of the religion, they start elevating people to the Divine Status, they reduce the Divine Assignments, they support their claims using refuted and weak religious texts and they become aggressive. These are the characteristics of the deviated sects in the Islamic history. On the other hand, when we are keen on the essence of our religion and on its foundations, without adding to them or omitting from them, we will be granted exaltedness and happiness.

((It was narrated that Jabir bin 'Abdullah said: "In his Khutbah the Messenger of Allah (PBUH) used to praise Allah as He deserves to be praised, then he would say: 'Whomsoever Allah (SWT) guides, none can lead him astray, and whomsoever Allah sends astray, none can guide. The truest of word is the Book of Allah and best of guidance is the guidance of Muhammad. The worst of things are those that are newly invented; every newly-invented thing is an innovation and every innovation is deviation, and every deviation is in the Fire.'"))

[An-Nasa'ee]

 Among the characteristics of the sincere Da'wah (calling to Allah) is to follow Allah's Path, because the Creator (i.e. Allah) is the Absolute Perfection, so is His Method. Thus, the one who calls to Allah should follow this method and should not innovate a new one. Another characteristic is to cooperate with other Muslims and to acknowledge their favor, for when the caller to Allah (Dai'yah) takes on his shoulder Muslims' concerns, he tends to cooperate with them instead of competing with them, and he will give credit to the favor of each one of them.

 As I have just said, the characteristics of the sincere Da'wah to Allah is following (the Divine Method), cooperating (with other Muslims) and acknowledging their favors. Accordingly, it is said, "Follow the religion and do not innovate, be humble and do not be arrogant, for there is no room in this religion for innovation and arrogance."

 In some cases, Da'wah to Allah might be self-centered and sugar coated with being Da'wah to Allah. Such Da'wah is marked with innovation instead of following the Divine Method, and with competition instead of cooperation, and they do not give credit to sh3er.

 Actually, Da'wah to Allah can be the most sacred deed (when it is served sincerely), for it is the craft of the Prophets, peace be upon them, but it also can be utilized by the opportunists and might be undermined by them till their Da'wah becomes vulgar and does not deserve more than a sarcastic grin.

 I would like to pay your attention to the fact that Tashree' (legislation) is one of the constituents of the Divine Assignment, and it is about the Orders and Prohibitions that are mentioned in the Noble Quran and the authenticated Prophetic Sunnah. I shall discuss this issue in details when I will tackle the two sources of Tashree' in the coming sections inshaallah.
