What is the wisdom behind the hadith in Minhaj Al Salikeen in the chapter of of impure things and removing them: 'Water should be sprinkled on the urine of a baby boy, and the urine of a baby girl should be washed away.'" Why is a baby girl's urine washed while the boy's urine is only sprinkled?

Ustadh AbdulAziz al-Haqqan

Some of the people of ilm said because for boys it stays in 1 place and doesn't spread out like girls, and Allah knows best.
