From Sahih Muslim (Hadith 6487):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:Do not revile my Companions, do not revile my Companions. By Him in Whose Hand is my life, if one amongst you would have spent as much gold as Uhud it would not amount to as much as one much on behalf of one of them or half of it
