Exercise restraint in delivering some of your religious verdicts, for you do not know what the Commander of Believers has introduced in the rites (of Hajj) after you (when you were away in Yemen). He (Abu Musa, ) met him (Hadrat Umar) subsequently and asked him (about it), whereupon 'Umar said: I know that Allah's Apostle (May peace be upon him) and also his Companions did that (observed Tamattu'), but I do not approve that the married persons should have intercourse with their wives under the shade of the trees, and then set out for Hajj with water trickling down from their heads.  

لَهُ رَجُلٌ رُوَيْدَكَ بِبَعْضِ فُتْيَاكَ فَإِنَّكَ لاَ تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي النُّسُكِ بَعْدُ حَتَّى لَقِيَهُ بَعْدُ فَسَأَلَهُ فَقَالَ عُمَرُ قَدْ عَلِمْتُ أَنَّ النَّبِيَّ ﷺ قَدْ فَعَلَهُ وَأَصْحَابُهُ وَلَكِنْ كَرِهْتُ أَنْ يَظَلُّوا مُعْرِسِينَ بِهِنَّ فِي الأَرَاكِ ثُمَّ يَرُوحُونَ فِي الْحَجِّ تَقْطُرُ رُءُوسُهُمْ  

“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).”  

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 ﷺ فَعَلَهُ وَأَصْحَابُهُ وَلَكِنِّي كَرِهْتُ أَنْ يَظَلُّوا بِهِنَّ مُعْرِسِينَ تَحْتَ الأَرَاكِ ثُمَّ يَرُوحُونَ بِالْحَجِّ تَقْطُرُ رُءُوسُهُمْ  

Do not rush in giving fatwas, for you do not know what Ameer al-Muʿmineen has decided with regard to Haji. When he met him later on, he asked him and ‘Umar said: I know that the Prophet ﷺ did it and his Companions did it, but I do not like [the people] to have intercourse with [their wives] beneath the arak trees and go out to Hajj with their heads dripping(from ghusl).  

لَهُ رَجُلٌ رُوَيْدَكَ بِبَعْضِ فُتْيَاكَ فَإِنَّكَ لَا تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي النُّسُكِ بَعْدَكَ حَتَّى لَقِيَهُ بَعْدُ فَسَأَلَهُ فَقَالَ عُمَرُ قَدْ عَلِمْتُ أَنَّ النَّبِيَّ ﷺ قَدْ فَعَلَهُ وَأَصْحَابُهُ وَلَكِنِّي كَرِهْتُ أَنْ يَظَلُّوا بِهِنَّ مُعَرِّسِينَ فِي الْأَرَاكِ ثُمَّ يَرُوحُونَ بِالْحَجٍّ تَقْطُرُ رُؤُوسُهُمْ

(Using translation from Muslim 1222)  

لَهُ رَجُلٌ رُوَيْدَكَ بِبَعْضِ فُتْيَاكَ فَإِنَّكَ لَا تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي النُّسُكِ بَعْدُ حَتَّى لَقِيتُهُ فَسَأَلْتُهُ فَقَالَ عُمَرُ «قَدْ عَلِمْتُ أَنَّ رَسُولَ اللهِ ﷺ قَدْ فَعَلَهُ وَلَكِنْ كَرِهْتُ أَنْ يَظَلُّوا مُعَرِّسِينَ بِهِنَّ فِي الْأَرَاكِ ثُمَّ يَرُوحُوا فِي الْحَجِّ تَقْطُرُ رُءُوسُهُمْ»  

"عَنْ أَبِى مُوسَى الأَشْعَرِى أَنَّهُ كَانَ يُفْتِى بالْمُتْعَةِ فَقَالَ لَهُ رَجُلٌ: رُوَيْدَكَ بِبَعْضِ فُتْيَاكَ، فَإنَّكَ لَا تَدْرِى مَا أَحْدَثَ أميرُ الْمُؤْمِنِينَ فِى النُّسُكِ بَعْدَكَ، حَتَّى لَقِيتهُ فَسَأَلْتُهُ، فَقَالَ عمَرُ: قَدْ عَلِمْتُ أَنَّ رَسُولَ الله ﷺ فَعَلَهُ وَأَصْحَابُه، وَلَكِنِّى كَرِهْتُ أَنْ يَظَلُّوا بِهِنَّ مُعَرِّسِينَ تَحْتَ الأَرَاكِ، ثُمَّ يَرُوحُونَ بِالْحَجِّ تَقْطُرُ رُءُوسُهُمْ".
