Prompted from this discussion, there are various opinions as to who we are allowed to add the suffix sallah Allahu allehe wa salam.
Allah and His angels send blessings on the Prophet: O ye that believe! Send ye blessings on him, and salute him with all respect. 33:56
From this ayah we can infer that we must use it for prophet Muhammad (SAAWS) but what about the other prophets?
We say in our prayers that Allah send his blessings to prophet Muhammad and Abraham, and his Aal (family), if that's the case, then we can use the suffix to more people other than Prophet Muhammad.
So who do we use this suffix for, Prophet Muhammad, Prophet Abraham, or all the prophets?
