Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated ‘Umar (Radi-Allahu ‘anhu):
Abu Bakr had a slave who used to give him some of his earnings. Abu Bakr
used to eat from it. One day he brought something and Abu Bakr ate from
it. The slave said to him, “Do you know what this is?” Abu Bakr then
enquired, “What is it?” The slave said, “Once, in the pre-Islamic period
of ignorance I foretold somebody’s future though I did not know this
knowledge of foretelling but I cheated him, and when he met me, he gave
me something for that service, and that is what you have eaten from.”
Then Abu Bakr put his hand in his mouth and vomited whatever was present
in his stomach.
