Umm Qais daughter of Mihsan told how she brought a young son of hers who was not yet weaned to God’s messenger. He set him on his lap, and the child passed water on his garment; so he called for water and sprinkled it, but did not wash it. (Bukhari and Muslim.)

وَعَن أم قيس بنت مُحصن: أَنَّهَا أَتَتْ بِابْنٍ لَهَا صَغِيرٍ لَمْ يَأْكُلِ الطَّعَامَ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَجْلَسَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي حِجْرِهِ فَبَالَ عَلَى ثَوْبِهِ فَدَعَا بِمَاء فنضحه وَلم يغسلهُ
