Omar bin ALI, from Abi Jaafar Mohammad bin Ali from his fathers, from the MESSENGER OF ALLAH (SAWW), who said:
ALLAH (SWT) gave me a covenant and said, “Listen.”
I said, “I am listening.”
ALLAH (SWT) said:
O MOHAMMAD (SAWW) ! Verily ALI (ASWS) is the flag of guidance after you. He is the Imam of My friends. He is the light of those who obey Me and he is My word to whom I have obliged the pious ones to be committed.
Those who love him love Me, and those who hate him hate Me. Give these glad tidings to ALI (ASWS) .
