He met with deadly dangers, acted justly and fairly, made use of everything belonging to him to pay full attention to give sincere advice; took pains, made every effort, and put his heart, mind, soul and life at the disposal of Thy mission to liberate the people from the yoke of ignorance and evil of bewilderment, but an evildoer, deceived with empty hopes of mean and worthless worldly gains, had pressed heavily on him, and sold out his share (eternal bliss) for the meanest and A lowest bargain, betrayed his "day of judgement" for a vulgar return, took pride in insolence, fell into the fathom-well of silly stupid follies, provoked Thee and Thy Prophet to anger, did as the harsh discordant, the hypocrite, the heavily burdened bearers of sin, condemned to Hellfire, advised to him, however, he (the Holy Imam), steadily, rightly and justly coped with them, till, in Thy obedience, gave his life after which his family was set adrift.
