He said: Abu Bakr Muhammad b. Umar al-Je'abi reported to me from ALI b. Ishaq al- Makhrami, who reported from Uthman b. Abdillah al-Shami, who reported from ibn Luhayah, from Abu Zura'h al-Hadhrami, from Umar b. ALI BIN ABI TALIB (ASWS), from his FATHER (ASWS), peace be upon him that:
The PROPHET (SAWW) , peace be upon him and his progeny, said: "O ALI (ASWS) ! With us ALLAH (SWT) completed His religion, the same way as He initiated it, and with us He will unite your hearts (in love) after the enmity and hatred."
