وَعَنْ عِيسَى بْنِ يَزْدَادَ، عَنْ أَبِيهِ
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«إِذَا بَالَ أَحَدُكُمْ فَلْيَنْثُرْ ذَكَرَهُ ثَلَاثَ مَرَّاتٍ»
The Messenger of Allah (sallallahu alayhi wa sallam) said: “When one of you passes urine, he should empty his penis three times”.
