Al-Arba’īn an-Nawawīyah Ḥadīth [16]

عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ أَنَّ رَجُلًا قَالَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَوْصِنِيْ، قَالَ: لَا تَغْضَبْ، فَرَدَّدَ مِرَارًا، قَالَ: لَا تَغْضَبْ. رَوَاهُ الْبُخَارِيُّ

16 – It is reported on the authority of Abī Hurayrah (may Allāh be pleased with him):

A man said to the Prophet (peace and blessings of Allāh be upon him): ‘Advise me’ So, he said: “Do not become angry.” The man repeated that several times, [and each time] he said: “Do not become angry.” [Reported by Bukhārī]
