The judge, Al-Moaafi bin Zakariyya, narrated from Mohammad bin Mazid, from Abu Karib Mohammad bin Alaa, from Ismail bin Sabih, from Abu Yunus, from Mohammad bin Al- Monkader, from Jabir bin Abdillah Al-Ansari, who said:
The MESSENGER OF ALLAH (SWT) said to ALI BIN ABI TALEB (ASWS):
Are you not pleased that you are to me as Harun was to Musa, except that there is no Prophet after me? And if there were to be one, it would have been you.
