[Machine] That the messenger of Allah ﷺ took a bath and whoever did not take a bath, it is not obligatory upon him. And I will inform you how this happened. The people used to work hard wearing woolen garments and working on their backs. Their mosque was small and the roof was made of huts. The messenger of Allah ﷺ went out one hot day and he was sweating in that woolen garment until the wind blew and it harmed some of them. The prophet ﷺ found those winds and said, "O people, if it is a day like this, then take a bath and let one of you touch the most of what he finds from his oil and perfume."
أَنْ أَغْتَسِلَ وَمَنْ لَمْ يَغْتَسِلْ فَلَيْسَ عَلَيْهِ بِوَاجِبٍ وَسَوْفَ أُخْبِرُكُمْ كَيْفَ هَذَا؟ كَانَ النَّاسُ مَجْهُودِينَ يَلْبَسُونَ الصُّوفَ وَيَعْمَلُونَ عَلَى ظُهُورِهِمْ وَكَانَ مَسْجِدُهُمْ ضَيِّقًا وَكَانَ السَّقْفُ إِنَّمَا هُوَ عَرِيشٌ فَخَرَجَ رَسُولُ اللهِ ﷺ يَوْمًا حَارًّا وَقَدْ عُرِقَ فِي ذَلِكَ الصُّوفِ حَتَّى ثَارَتْ رِيَاحٌ وَحَتَّى أَذًى بِذَلِكَ بَعْضُهُمْ بَعْضًا فَوَجَدَ النَّبِيُّ ﷺ تِلْكَ الرِّيَاحَ فَقَالَ رَسُولُ اللهِ ﷺ «أَيُّهَا النَّاسُ إِذَا كَانَ هَذَا الْيَوْمُ فَاغْتَسِلُوا وَلْيَمَسَّ أَحَدُكُمْ أَمْثَلَ مَا يَجِدُ مِنْ دُهْنِهِ وَطِيبِهِ»
