"They argued about Ghusl in the presence of the messenger of Allah ﷺ. One of the people said: 'I perform Ghusl in such-and-such a manner.' The Messenger of Allah ﷺ said: 'As for me, I pour three handfuls of water over my head.'" (Using translation from Nasāʾī 250)
تَمَارُوا فِي الْغُسْلِ عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ بَعْضُ الْقَوْمِ إِنِّي لَأَغْتَسِلُ كَذَا وَكَذَا فَقَالَ رَسُولُ اللهِ ﷺ «أَمَّا أَنَا فَإِنِّي أُفِيضُ عَلَى رَأْسِي ثَلَاثَ أَكُفٍّ»
