وَعَن عبد الله بن عمر
قَالَ كَانَتِ الصَّلَاةُ خَمْسِينَ وَالْغُسْلُ مِنَ الْجَنَابَةِ سبع مرار وَغسل الْبَوْل من الثَّوْب سبع مرار فَلَمْ يَزَلْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُسْأَلُ حَتَّى جعلت الصَّلَاة خمْسا وَالْغسْل من الْجَنَابَة مرّة وَغسل الْبَوْل من الثَّوْب مرّة
The original requirement was fifty times of prayer, seven washings to remove sexual defilement, and seven washings when urine fell on a garment. God’s messenger therefore kept on making requests till five times of prayer were appointed, one washing for sexual defilement, and one washing of a garment because of urine.
