Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، - وَاللَّفْظُ لَهُ - قَالاَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنْ إِبْرَاهِيمَ بْنِ أَبِي مُوسَى، عَنْ أَبِي مُوسَى، أَنَّهُ كَانَ يُفْتِي بِالْمُتْعَةِ فَقَالَ لَهُ رَجُلٌ رُوَيْدَكَ بِبَعْضِ فُتْيَاكَ فَإِنَّكَ لاَ تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي النُّسُكِ بَعْدُ . حَتَّى لَقِيتُهُ فَسَأَلْتُهُ فَقَالَ عُمَرُ قَدْ عَلِمْتُ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَدْ فَعَلَهُ وَلَكِنْ كَرِهْتُ أَنْ يَظَلُّوا مُعَرِّسِينَ بِهِنَّ فِي الأَرَاكِ ثُمَّ يَرُوحُوا بِالْحَجِّ تَقْطُرُ رُءُوسُهُمْ .
It was narrated that Abu Musa said that: he used to issue Fatwas concerning Tamattu' Then a man said to him: "Withhold some of your Fatwas ,for you do not know what the commander of the Believers introduced into the rites subsequently." Then when I met him, I asked him. 'Umar said: "I know that the Messenger of Allah and his companions did it, but I did not like that people should lay with their wives in the shade of the Arak trees, and then go out for Hajj with their heads dripping."
