The MESSENGER OF ALLAH (SWT), said:
On the night of Me’raaj, ALLAH (SWT) entrusted three statements to me.
ALLAH (SWT) said, “O MOHAMMAD (SAWW) !”
“I am at your service , O my Lord,”, I replied.
ALLAH (SWT) said, “ALI (ASWS) is the IMAM of the pious, the glorified leader of the companions of Paradise, and the leader of the believers.”
