Abi Ubaida bin MOHAMMAD bin Ammar bin Yasir, from his father, from Ammar bin Yasir, from the MESSENGER OF ALLAH (SAWW), who said:
I advise those who believe in me and accept the Wilayat of ALI BIN ABI TALEB (ASWS) to understand that those who accept ALI (ASWS)’s Wilayat accept my Wilayat, and those who accept my Wilayat accept the Wilayat of ALLAH (SWT).
Those who love ALI (ASWS) love me, and those who love me love ALLAH (SWT). Those who hate ALI (ASWS) hate me, and those who hate me hate ALLAH (SWT).
