And the Exalted says:
“They worship, apart from Allah, things that can neither harm them nor benefit them, and they say, ‘These are our intercessors with Allah.’ Say, ‘Are you informing Allah of something He does not know in the heavens or on earth?’” (Yūnus 10:18) (1)
He also says, concerning the man in Sūrah Yā Sīn:
“Why should I not worship the One who created me, and to Him you will be returned? Shall I take deities other than Him? If the All-Merciful intends me any harm, their intercession will not help me in the least, nor can they rescue me. Truly, I would then be in manifest error. I have believed in your Lord, so listen to me.” (Yā Sīn 36:22–25) (2)
He, the Most High, says:
“You have come to Us one by one, just as We created you the first time, and you have left behind everything We bestowed upon you. Nor do We see with you your intercessors whom you claimed were partners with you; all ties between you are now severed, and what you used to claim has deserted you.” (al-Anʿām 6:94) (3)
And He says:
“You have, apart from Him, no protector and no intercessor.” (as-Sajdah 32:4) (4)
He further says:
“Warn with it those who fear being gathered to their Lord: they shall have, apart from Him, no protector and no intercessor—perhaps they will become mindful.” (al-Anʿām 6:51) (5)
On this matter people have split into three groups: two extremes and a middle course. The polytheists—and those who sided with them among the innovators of the People of the Book, such as the Christians—as well as the innovators within this ummah affirmed a kind of intercession that the Qur’an itself negates (6). The Khārijites and the Muʿtazilites, on the other hand, denied the intercession of our Prophet, peace and blessings be upon him, on behalf of those in his community who commit major sins (7).
