“Abu Ja‘far (a.s.), has said, ‘The Messenger of Allah would do something over the grave of the people from the tribe of banu Hashim and he would not do on other Muslims’ graves. After performing Salah (prayer) for a deceased from banu Hashim, sprinkling water over his grave, he would place his hand over the grave while his fingers pressed in the clay. Strangers or travelers who came in the town and saw a new grave with marks of the fingers of the Messenger of Allah on it could tell that someone from banu Hashim has died. They would ask, ‘Who from the family of Muhammad, O Allah grant compensation to Muhammad and his family worthy of their services to Your cause, has died?”’
