وَعَنْ شُعْبَةَ قَالَ: إِنَّ ابْنَ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ
كَانَ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ يفرغ بِيَدِهِ الْيُمْنَى عَلَى يَدِهِ الْيُسْرَى سَبْعَ مِرَارٍ ثُمَّ يَغْسِلُ فَرْجَهُ فَنَسِيَ مَرَّةً كَمْ أَفْرَغَ فَسَأَلَنِي كم أفرغت فَقُلْتُ: لَا أَدْرِي فَقَالَ: لَا أُمَّ لَكَ وَمَا يَمْنَعُكَ أَنْ تَدْرِيَ ثُمَّ يَتَوَضَّأُ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ يُفِيضُ عَلَى جِلْدِهِ الْمَاءُ ثُمَّ يَقُولُ هَكَذَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يتَطَهَّر
When Ibn Abbas washed because of seminal defilement he emptied water seven times from his right hand over his left hand, then washed his private parts. Once he forgot how often he had emptied it, so he asked Shuba, but he replied that he did not know, so he said, “You should be ashamed of yourself. What prevents you from knowing?” Then he would perform his ablution for prayer, then pour water over his body and say, “Thus was God’s messenger accustomed to purify himself.”
