I heard al-Sadiq Abu `Abdillah (as) say: When al-Husayn b. `Ali (as) was born, Allah ordered Jibra’il that he descend with a thousand angels and offer congratulations to the Messenger of Allah (s) from Allah and from Jibra’il. He said: So Jibra’il descended and he passed by an island in the sea wherein was an angel, named Futrus, who was from the bearers (of the Throne). Allah had dispatched him for something and he had delayed it. So, He broke his wings and banished him to that island. He worshipped Allah therein for seven hundred years until al-Husayn b. `Ali (as) was born. The angel said to Jibra’il: O Jibra’il! Where do you intend (i.e. to go)? He said: Allah has bestowed a bounty on Muhammad. So, I have been sent to offer him congratulations from Allah and myself. He said: O Jibra’il! Carry me with you; perhaps Muhammad (s) will pray for me. He said: So, he carried him. He said: When Jibra’il entered the Prophet’s presence, he conveyed to him the congratulations from Allah and himself and informed him about the state of Futrus. The Prophet (s) said: Say to him: Rub (yourself) against this newborn and revert to your abode. He said: So Futrus rubbed (himself) against al-Husayn b. `Ali (as) and he ascended. He said: O Messenger of Allah! Your Nation will certainly kill him soon, and upon me is the remuneration for him. A visitor shall not visit him but that I will notify him and a Muslim shall not send his salutation upon him but that I will convey to him his salaam. A praying one shall not say a prayer (benediction of Allah) upon him but that I will convey to him his prayer. Then he ascended.
