Abu Sa'eed narrated the Messenger of Allah (ﷺ) said:
"Indeed in my Ummah are those who intercede for large groups of people, and among them (there are) who intercede for a tribe, and among them (there are) who intercede for a group, and among them (there are) who intercede for a man, until they are admitted to Paradise."
