All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.
The Sunnah contains Hadiths indicating
the rulings on the urine of a baby boy or girl.
Um Qays bint Mihsan narrated that she brought her little son who has not yet eaten solid food to the Messenger of Allah (peace be upon him). The Messenger of Allah (peace be upon him) sat him on his lap, and he urinated on his garment, so he called for some water and poured it (over the soiled area), but did not wash it.
Related by the Six Hadith Compilers (Al-Bukhari, Muslim, Abu Dawud, Al-Tirmidhy, Al-Nasa'y, and Ibn Majah).
It is also related on the authority of
`Aly ibn Abu Talib (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said:
The urine of a baby boy should be sprinkled over with water and the urine of a baby girl should be washed.
Qatadah commented, “This (rule) applies as long as they have not yet eaten solid food; once they start to eat solid food, then it must be washed in both cases.”
Al-Tirmidhy who classed it as Hadith Hasan (a Hadith whose chain of narration contains a narrator with weak exactitude, but is free from eccentricity or blemish).
Accordingly, you must wash off the urine that splashes onto you from a baby girl or boy who has started eating solid food. In case it is the urine of a baby boy who has not yet eaten solid food, it will be sufficient to sprinkle water over his urine and there will be no need to wash or wring out the garment. The same applies to Ihram clothes; it should be washed if soiled with the urine of a baby girl or that of a baby boy who has started eating solid food, and can only be sprinkled with water if soiled with the urine of a baby boy who has not yet started to eat solid food. (Part No. 5; Page No. 371) Moreover, if you have no clothes other than the Ihram wear, you can sprinkle water over it if soiled with the urine of a baby boy who has not yet started to eat solid food. You will have to wash the part of your clothing that gets soiled with the urine of a baby girl or boy who has started to eat solid food but in a secure place that protects you from uncovering your `Awrah (parts of the body that must be covered in public) in front of other people, unless it be your wife.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
