كتاب المناسك
Read the English translation first, with the original Arabic directly underneath.
It was narrated from Ibrahim bin Abu Musa:
“Abu Musa Al-Ash’ari used to issue rulings concerning Tamattu’. Then a man said to him: ‘Withhold some of your rulings, for you do not know what the Commander of the Believers has introduced into the rites after you.’ (Abu Musa said:) ‘Then when I met him later on, I asked him.’ ‘Umar said: ‘I know that the Messenger of Allah (ﷺ) and his Companions did it, but I did not like that people should lie with their wives in the shade of the Arak trees and then go out for Hajj with their heads dripping,’ (i.e. due to the bath after sexual relations).”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، ح وَحَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنِي أَبِي قَالاَ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنْ إِبْرَاهِيمَ بْنِ أَبِي مُوسَى، عَنْ أَبِي مُوسَى الأَشْعَرِيِّ، أَنَّهُ كَانَ يُفْتِي بِالْمُتْعَةِ فَقَالَ لَهُ رَجُلٌ رُوَيْدَكَ بَعْضَ فُتْيَاكَ فَإِنَّكَ لاَ تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي النُّسُكِ بَعْدَكَ . حَتَّى لَقِيتُهُ بَعْدُ فَسَأَلْتُهُ فَقَالَ عُمَرُ قَدْ عَلِمْتُ أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ فَعَلَهُ وَأَصْحَابُهُ وَلَكِنِّي كَرِهْتُ أَنْ يَظَلُّوا بِهِنَّ مُعْرِسِينَ تَحْتَ الأَرَاكِ ثُمَّ يَرُوحُونَ بِالْحَجِّ تَقْطُرُ رُءُوسُهُمْ .
