Narrated Abu As-Samh (rad):

Allah’s Messenger (ﷺ) said: “The urine of a baby girl should be washed off and the urine of baby boy should be sprinkled (with water)”. [Reported by Abu Da’ud and An-Nasa’i and Al-Hakim graded it Sahih (sound)].

وَعَنْ أَبِي اَلسَّمْحِ ‏- رضى الله عنه ‏- قَالَ: قَالَ اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-{ يُغْسَلُ مِنْ بَوْلِ اَلْجَارِيَةِ, وَيُرَشُّ مِنْ بَوْلِ اَلْغُلَامِ } أَخْرَجَهُ أَبُو دَاوُدَ, وَالنَّسَائِيُّ, وَصَحَّحَهُ اَلْحَاكِم ُ [1]‏ .‏
