Asking Permission
Chapter: Two to have a secret talk in a gathering of more than three
Narrated `Abdullah:
One day the Prophet (ﷺ) divided and distributed something amongst the people whereupon an Ansari man said, "In this division Allah's Countenance has not been sought." I said, "By Allah! I will go (and inform) the Prophet." So I went to him while he was with a group of people, and I secretly informed him of that, whereupon he became so angry that his face became red, and he then said, "May Allah bestow His Mercy on Moses (for) he was hurt more than that, yet he remained patient."
