Abu-Bakr narrates that the Messenger of Allah (ص) said:
“God created from the light of Ali bin Abi Talib angels who glorify and sanctify Him, and its reward is recorded and written for the lovers of Ali and the lovers of his children”
Kharazmi, Maqtal al-Husain (a.s.), V.1, page 97; Ibn Uqdah Kufi, Fazail Amirul-Mu’minin (a.s.), page 32; Kharazmi has narrated it’s like from Omar ibn Khattab (Al-Manaqib, page 329).
