The Messenger of Allah ﷺ said to us: When one of you becomes angry while standing, he should sit down. If the anger leaves him, well and good; otherwise he should lie down.
إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَنَا إِذَا غَضِبَ أَحَدُكُمْ وَهُوَ قَائِمٌ فَلْيَجْلِسْ فَإِنْ ذَهَبَ عَنْهُ الْغَضَبُ وَإِلاَّ فَلْيَضْطَجِعْ
