عَنْ جَارِيَةَ بْنِ قُدَامَةَ السَّعْدِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَجُلًا سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ يَا رَسُولَ اللَّهِ قُلْ لِي قَوْلًا يَنْفَعُنِي وَأَقْلِلْ لَعَلِّي أَعِيهِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((لَا تَغْضَبْ)) فَأَعَادَ عَلَيْهِ حَتَّى أَعَادَ عَلَيْهِ مِرَارًا كُلَّ ذَلِكَ يَقُولُ ((لَا تَغْضَبْ))
It is narrated from Sayyiduna Jariyah bin Qudamah Sa'di, may Allah be pleased with him, that a man asked the Messenger of Allah, peace and blessings be upon him, and said: O Messenger of Allah! Tell me something beneficial, but it should be brief so that I can remember it. The Prophet, peace and blessings be upon him, said: Do not become angry. Then the Prophet, peace and blessings be upon him, repeated this several times, and each time he said: Do not become angry.
