Say: What thing is the weightiest in testimony? Say: Allah is witness between you and me; and this Quran has been revealed to me that with it I may warn you and whomsoever it reaches. Do you really bear witness that there are other gods with Allah? Say: I do not bear witness. Say: He is only one Allah, and surely I am clear of that which you set up (with Him).

And We have not sent before you but men from (among) the people of the towns, to whom We sent revelations. Have they not then travelled in the land and seen what was the end of those before them? And certainly the abode of the hereafter is best for those who guard (against evil); do you not then understand?

This is of what your Lord has revealed to you of wisdom, and do not associate any other god with Allah lest you should be thrown into hell, blamed, cast away.
