Intercession

He knows what is [presently] before them and what will be after them, and they cannot intercede except on behalf of one whom He approves. And they, from fear of Him, are apprehensive.

[Qur'aan 21:28]

And intercession does not benefit with Him except for one whom He permits. [And those wait] until, when terror is removed from their hearts, they will say [to one another], "What has your Lord said?" They will say, "The truth." And He is the Most High, the Grand.

[Qur'aan 34:23]

Narrated Anas ibn Malik:

The Prophet (sallallaahu alayhi wa sallam) said: My intercession will be for those of my people who have committed major sins.

[Sunan Abi Dawud Hadith No. 4739]
