Ubaidullah bin 'Abdullah bin 'Utba bin Mas'ud said: Umm Qais, daughter of Mihsan, was among the earliest female emigrants who took the oath of allegiance to the Messenger of Allah ( صلی اللہ علیہ وسلم ) , and she was the sister of 'Ukkasha bin Mihsan, one amongst the sons of Asad bin Khuzaima. He (the narrator) said: She (Umm Qais) told me that she came to the Messenger of Allah ( صلی اللہ علیہ وسلم ) (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 ( صلی اللہ علیہ وسلم ) . The Messenger of Allah ( صلی اللہ علیہ وسلم ) 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.
