The Messenger of Allah ﷺ said, "Do not insult my companions. By the One in whose hand my soul rests, if any of you were to spend gold equal to Mount Uhud, it would not equal a handful of one of them, nor even half of that."
حدثنا مسدد حدثنا أبو معاوية عن الأعمش عن أبي صالح
قال رسول الله ﷺ لا تسبوا أصحابي فوالذي نفسي بيده لو أنفق أحدكم مثل أحد ذهبا ما بلغ مد أحدهم ولا نصيفه
