When the man later returned and claimed his money from my father, my father promised to return it to him the following day (not knowing where he was going to acquire the money from). My father then went to the blessed grave of Rasulullah (sallallahu ‘alaihi wasallam) where he made du‘aa for the entire night, sometimes at the grave and sometimes at the mimbar, begging Allah Ta‘ala for a way out of his problem.

In the latter portion of the night, he heard a voice coming to him from the darkness near the grave saying, “O Muhammed, take this.” My father reached out with his hand and a bag was given to him. In the bag, he found eighty gold coins!
