[Machine] She brought her son to the Prophet Muhammad ﷺ who had not reached the age to eat food yet, so he made him sit in his lap. The child urinated on him, so the Prophet called for water and poured it on the area, but did not wash it.  

الدارمي:٧٦٨أَخْبَرَنَا عُثْمَانُ بْنُ عُمَرَ حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ وَحَدَّثَنَاهُ عَنْ يُونُسَ أَيْضًا عَنِ الزُّهْرِيِّ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ عَنْ أُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ

أَنَّهَا أَتَتِ النَّبِيَّ ﷺ بِابْنٍ لَهَا لَمْ يَبْلُغْ أَنْ يَأْكُلَ الطَّعَامَ فَأَجْلَسَهُ فِي حِجْرِهِ فَبَالَ عَلَيْهِ «فَدَعَا بِمَاءٍ فَنَضَحَهُ وَلَمْ يَغْسِلْهُ»
