The Messenger of Allah ﷺ said one day in his sermon, "Allah has revealed to me that you should be humble toward one another, so that no one boasts over another, and no one wrongs another."
أن رسول الله ﷺ قال يوم في خطبته: إن الله أوحى إلي أن تواضعوا حتى لا يفخر أحد على أحد، ولا يبغي أحد على أحد.
Muslim narrated it in the Book of Paradise and the Description of its Bliss (2865:64), from Abu Ammar Husayn bin Hurayth, who said, Fadl bin Musa told us, from Husayn, from Matar, who said, Qatada told me, from Mutarrif bin Abdullah bin Shikhir, from Iyad bin Himar, and he related it.
