Sulaym narrates from Jabir ibn Abdullah Ansari. He said: “The Messenger of Allah (SAW) came to us with a branch of dates, which had its skin peeled off and was fresh. At that time we were in his mosque. He started hitting us with that and said: “Do not sleep in the mosque.”
Jabir continues: “We left and Ali (AS) also decided to leave with us but the Holy Prophet (SAW) said: “O my brother, where are you going? For you all is lawful in the mosque that is lawful for me. Your status to is the same as what Haroon had to Musa. Allah commanded Musa to build a pure mosque and except his two sons Shabir and Shabbar, no one remains in there.
O my brother, By Him in Whose Hands lies my life, surely you are the one to make distant from my fountain with your hands, like a man separates from that camel who has an itch. I can see your place near my fountain. You have a stick with you which is from shrubs.”
