Yahya related to me from Malik that Yahya ibn Said said, "A Bedouin came into the mosque and uncovered his private parts to urinate. The people called out to him and began to raise their voices but the Messenger of Allah ﷺ said ,'Let him be. 'So they let him be and he urinated. Then the Messenger of Allah ﷺ ordered a bucketful of water to be brought and it was poured on the place."
أَنَّهُ قَالَ دَخَلَ أَعْرَابِيٌّ الْمَسْجِدَ فَكَشَفَ عَنْ فَرْجِهِ لِيَبُولَ فَصَاحَ النَّاسُ بِهِ حَتَّى عَلاَ الصَّوْتُ فَقَالَ رَسُولُ اللَّهِ ﷺ اتْرُكُوهُ فَتَرَكُوهُ فَبَالَ ثُمَّ أَمَرَ رَسُولُ اللَّهِ ﷺ بِذَنُوبٍ مِنْ مَاءٍ فَصُبَّ عَلَى ذَلِكَ الْمَكَانِ
