عَنْ يُونُسَ عَنِ الْحَسَنِ أَنَّ عُمَرَ رَضِيَ اللَّهُ عَنْهُ أَرَادَ أَنْ يَنْهَى عَنْ مُتْعَةِ الْحَجِّ فَقَالَ لَهُ أُبَيُّ (بْنُ كَعْبٍ) رَضِيَ اللَّهُ عَنْهُ: لَيْسَ ذَلِكَ لَكَ، قَدْ تَمَتَّعْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَلَمْ يَنْهَنَا، فَأَضْرَبَ عَنْ ذَلِكَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ، وَأَرَادَ أَنْ يَنْهَى عَنْ حُلَلِ الْحِبْرَةِ، لِأَنَّهَا تُصْبَغُ بِالْبَوْلِ، فَقَالَ لَهُ أُبَيٌّ: لَيْسَ ذَلِكَ لَكَ، قَدْ لَبِسَهُنَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَلَبِسْنَاهُنَّ فِي عَهْدِهِ
It is narrated from Hasan that when Sayyiduna Umar (may Allah be pleased with him) intended to prohibit Hajj Tamattu', Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) said to him: "You cannot prohibit Hajj Tamattu', because we performed this Hajj in the company of the Messenger of Allah (peace and blessings be upon him) and the Messenger of Allah (peace and blessings be upon him) did not stop us from it." But Sayyiduna Umar (may Allah be pleased with him) turned away from his statement and did not pay any attention to it. Then Sayyiduna Umar (may Allah be pleased with him) wanted to prohibit Yemeni cloaks because they were dyed with urine, but Sayyiduna Ubayy (may Allah be pleased with him) said to him: "You cannot prohibit this either, because the Noble Prophet (peace and blessings be upon him) also wore them and in his time we used to wear them."
