Umm Qais, daughter of Mihsan, was among the earliest female emigrants who took the oath of allegiance to the Messenger of Allah ﷺ, and she was the sister of 'Ukkasha b. Mihsan, one amongst the sons of Asad b. Khuzaima. He (the narrator) said: She (Umm Qais) told me that she came to the Messenger of Allah (may peace he upon him) with her son and he had not attained the age of eating food. He (the narrator, 'Ubaidullah), said: She told me that her son passed urine in the lap of the Messenger of Allah ﷺ. The Messenger of Allah ﷺ sent for water and sprayed it over his garment (over that part which was contaminated with the urine of the child) and he did not wash it thoroughly.  

أَنَّ أَمَّ قَيْسٍ بِنْتَ مِحْصَنٍ وَكَانَتْ مِنَ الْمُهَاجِرَاتِ الأُوَلِ اللاَّتِي بَايَعْنَ رَسُولَ اللَّهِ ﷺ وَهِيَ أُخْتُ عُكَّاشَةَ بْنِ مِحْصَنٍ أَحَدُ بَنِي أَسَدِ بْنِ خُزَيْمَةَ قَالَ أَخْبَرَتْنِي أَنَّهَا أَتَتْ رَسُولَ اللَّهِ ﷺ بِابْنٍ لَهَا لَمْ يَبْلُغْ أَنْ يَأْكُلَ الطَّعَامَ قَالَ عُبَيْدُ اللَّهِ أَخْبَرَتْنِي أَنَّ ابْنَهَا ذَاكَ بَالَ فِي حِجْرِ رَسُولِ اللَّهِ ﷺ فَدَعَا رَسُولُ اللَّهِ ﷺ بِمَاءٍ فَنَضَحَهُ عَلَى ثَوْبِهِ وَلَمْ يَغْسِلْهُ غَسْلاً  

[Machine] Narrated by Umm Qais, the daughter of Muhassin, who was one of the early emigrant women who pledged allegiance to the Messenger of Allah ﷺ . She was the sister of Ukkasha bin Muhassin. Umm Qais said that she brought her son to the Messenger of Allah ﷺ who had not yet reached the age of eating solid food. He had a wet bed, so the Messenger of Allah ﷺ called for water and poured it on the boy's urine without washing it.  

عَنْ أُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ وَكَانَتْ مِنَ الْمُهَاجِرَاتِ الْأُوَلِ اللَّاتِي بَايَعْنَ رَسُولَ اللهِ ﷺ وَهِيَ أُخْتُ عُكَّاشَةَ بِنْتِ مِحْصَنٍ أَنَّهَا «أَتَتْ رَسُولَ اللهِ ﷺ بِابْنٍ لَهَا لَمْ يَبْلُغْ أَنْ يَأْكُلَ الطَّعَامَ فَبَالَ فِي حِجْرِ النَّبِيِّ ﷺ فَدَعَا رَسُولُ اللهِ ﷺ بِمَاءٍ فَنَضَحَهُ عَلَى بَوْلِهِ وَلَمْ يَغْسِلْهُ»
