Hadith no 220 and 221 are repeats. Read here.
Narrated ‘Aisha (the mother of faithful believers):
A child was brought to Allah’s Apostle and it urinated on the garment of the Prophet. The Prophet asked for water and poured it over the soiled place.
He did not panic, nor threw the child at someone, nor got angry. He was that awesome!
Now imagine what you’ll do if a kid urinates on your clothes. We’re repulsed by their pukes, let alone urine and feces.
Lesson: be more kind to kids and do not hate them for doing something they don’t have control over. :)
