Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Anas that the Messenger of Allah, peace and blessings be upon him, said: I have been harmed in the way of Allah as no one else has been harmed, and I have been frightened in the way of Allah as no one else has been frightened. And indeed, there have come upon me three days and nights in which there was not even such food for me and Bilal that any living being could eat, except for that amount which Bilal could conceal under his armpit.
