Hasan bin Ahmad bin Sokhtweyh Al-Mojawer narrated from Mohammad bin Ahmad Al- Baghdadi, from Isa bin Mihran, from Yahya bin Abdil Hamid Al-Hamani, from Qays bin Rabee’, from Aamash, from Abi Wael, from Abdullah bin Masoud, who said:
The MESSENGER OF ALLAH (SWT) said:
The first inhabitants of the heavens to take ALI BIN ABI TALEB (ASWS) as a brother, were Israfil, then Mikaeel, and then Jibraeel.
The first ones to love him were the carriers of the Throne, then Rezwan, the keeper of Paradise, and then the angel of death.
The angel of death is as merciful to those who love ALI BIN ABI TALEB (ASWS) as he is to the Prophets.
