Musnad Ahmad Hadith 21230

It is narrated from Ubayy bin Ka'b (may Allah be pleased with him) that on the occasion of the Battle of Uhud, sixty-four from the Ansar and six from the Muhajireen, as well as Hamza (may Allah be pleased with him), were martyred. The companions (may Allah be pleased with them) said that if after today there comes another opportunity to fight the polytheists, we will take revenge with interest. Thus, on the day of the conquest of Makkah, an unknown man said, "After today, the Quraysh will not remain." Upon this, the announcer of the Holy Prophet (ﷺ) proclaimed that security is granted to every black and white except for such and such persons whose names the Holy Prophet (ﷺ) mentioned. Then Allah Almighty revealed this verse: "If you want to take retribution, then inflict only as much punishment as was inflicted upon you, and if you are patient, then patience is best for those who are patient." Upon this, the Holy Prophet (ﷺ) said, "Withhold your hand from the Quraysh."
