"Teach me something that is not too much for me so that, perhaps, I may abide by it." He ﷺ said: "Do not get angry." He repeated that (the request) a number of times, each time he replied: 'Do not get angry."  

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ قَالَ عَلِّمْنِي شَيْئًا وَلاَ تُكْثِرْ عَلَىَّ لَعَلِّي أَعِيهِ قَالَ لاَ تَغْضَبْ فَرَدَّدَ ذَلِكَ مِرَارًا كُلُّ ذَلِكَ يَقُولُ لاَ تَغْضَبْ
