On the authority of Abu Hurayrah (may Allah be pleased with him):

A man said to the Prophet ﷺ, “Counsel me,” so he ﷺ said, “Do not become angry.” The man repeated [his request for counsel] several times, and [each time] he ﷺ said, “Do not become angry.”

[Al-Bukhari]

عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ أَنَّ رَجُلًا قَالَ لِلنَّبِيِّ ﷺ أَوْصِنِي. قَالَ: لَا تَغْضَبْ، فَرَدَّدَ مِرَارًا، قَالَ: لَا تَغْضَبْ" . [رَوَاهُ الْبُخَارِيُّ].
