In the name of Allah, the most Gracious, the most Merciful
Praise be to Allah, the Lord of the Worlds. The good end will ultimately be for the righteous people! May Allah's Peace and blessings be upon His servant and Messenger, the best of His creation who was entrusted with His Revelation, our Prophet and Imam, Muhammad Ibn `Abdullah, his Family, his Companions, and those who follow in his footsteps until the Day of Resurrection.
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
O mankind! Worship your Lord (Allâh), Who created you and those who were before you so that you may become AlMuttaqûn (the pious See V.2:2). Who has made the earth a resting place for you, and the sky as a canopy, and sent down water (rain) from the sky and brought forth therewith fruits as a provision for you. Then do not set up rivals unto Allâh (in worship) while you know (that He Alone has the right to be worshipped).
It is the duty of every Prophet whom Allah sent to guide his followers to what he knew was good for them and warn them against what he knew was bad for them. (Related by Muslim in his Sahih).
The believers, men and women, are Auliyâ' (helpers, supporters, friends, protectors) of one another; they enjoin (on the people) AlMa'rûf (i.e. Islâmic Monotheism and all that Islâm orders one to do), and forbid (people) from AlMunkar (i.e. polytheism and disbelief of all kinds, and all that Islâm has forbidden); they perform AsSalât (IqâmatasSalât), and give the Zakât, and obey Allâh and His Messenger. Allâh will have His Mercy on them. Surely Allâh is AllMighty, AllWise.
O you who believe! Take not as (your) Bitânah (advisors, consultants, protectors, helpers, friends) those outside your religion (pagans, Jews, Christians, and hypocrites) since they will not fail to do their best to corrupt you. They desire to harm you severely. Hatred has already appeared from their mouths, but what their breasts conceal is far worse. Indeed We have made plain to you the Ayât (proofs, evidence, verses) if you understand.
staying among them. Some people of the Salaf were of the view that those people become disbelievers because of their support of the Mushriks, which makes them one of them. Whoever supports the Mushriks against the Muslims is an apostate. Allah (Exalted be He) says, And if any amongst you takes them as Auliyâ', then surely he is one of them. Verily, Allâh guides not those people who are the Zâlimûn (polytheists and wrongdoers and unjust).
Verily, as for those whom the angels take (in death) while they are wronging themselves (as they stayed among the disbelievers even though emigration was obligatory for them)
Moreover,Abu Dawud, AlTirmidhy, and AlNasa'y related through an authentic Isnad on the authority of Jarir Ibn `Abdullah AlBajaly that the Prophet (peace be upon him) said, I am not responsible for any Muslim who stays among the Mushriks.
AlNisa'y(may Allah be merciful with him) related through an authentic Isnad that the Prophet (peace be upon him) said, "Allah does not accept any deeds from a Mushrik, after having embraced Islam, until he separates himself from the Mushriks."
