Mu'awiyah ibn AbuSufyan asked his sister Umm Habibah, the wife of the Prophet ﷺ: Would the apostle of Allah ﷺ pray in the clothe in which he had an intercourse? She said: Yes, when he would not see any impurity in it. (Using translation from Abū Dāʾūd 366)   

أَنَّهُ سَأَلَ أُمَّ حَبِيبَةَ هَلْ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي فِي الثَّوْبِ الَّذِي يُضَاجِعُكِ فِيهِ؟ قَالَتْ نَعَمْ إِذَا لَمْ يَرَ فِيهِ أَذًى

عَنْ أُخْتِهِ أُمِّ حَبِيبَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهُ سَأَلَهَا هَلْ كَانَ النَّبِيُّ ﷺ يُصَلِّي فِي الثَّوْبِ الَّذِي يُجَامِعُهَا فِيهِ؟ قَالَتْ نَعَمْ إِذَا لَمْ يَرَ فِيهِ أَذًى
