A person within close ciricle of Imam says that he was too puntual for performing mid-night prayers and never missed it.
Imam’s daughter-in-law has recalled throgh a series of memoirs that the great leader of Muslim world used to shed tears while worshiping for God the Almighty at mid-nights.
He used to perform prayers and recite supplications and the holy Quran and dealt each night as night of glory and destiny.
Imam used to shed tears during worship to such an extent that he needed not only tissue papers but towel to dry them.
It seemed that he was constantly spiritualy transformed during prayers and divine light could be seen on his face.
