Allah—exalted be He—has said concerning the people of felicity:
“Race toward forgiveness from your Lord and a Garden whose breadth is like the breadth of the heavens and the earth, prepared for those who believe in Allah and His messengers.”
(Sūrat al-Ḥadīd 57:21)
He thus made it plain that Paradise has been prepared for those who believe in Allah and in His messengers. He also said:
“Whenever guidance comes to you from Me, then whoever follows My guidance shall neither go astray nor become miserable. But whoever turns away from My remembrance will have a constricted life, and on the Day of Resurrection We shall raise him blind. He will say, ‘My Lord, why have You raised me blind when I used to see?’ He will be told, ‘Thus it is: Our signs came to you and you forgot them, and today you yourself are forgotten.’”
(Sūrat Ṭā Hā 20:123–126)

Such people are upon guidance from their Lord, and it is they who are the successful.”
(Sūrat al-Baqarah 2:2–5)
For this reason we recite in al-Fātiḥah:
“Guide us to the straight path—the path of those upon whom You have bestowed favor, not of those who have incurred anger nor of those who are astray.”
Those who have incurred anger and those who are astray are the people of misery and deviation; it is about them that He said:
“Indeed, the wicked are in error and madness.”
(Sūrat al-Qamar 54:47)
They stand in stark opposition to the people of guidance and success. The latter—who possess both knowledge and felicity—are the followers of the revealed Book. Hence, anyone who believes in part of the Book and disbelieves in another part—like the Jews and the Christians—cannot belong to this company. How much less, then, can one who does not believe in the Book at all, but is among those who
