"The Messenger of Allah was cupped while he was a Muhrim."  

الترمذي:٨٣٩حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ طَاوُسٍ وَعَطَاءٍ عَنِ ابْنِ عَبَّاسٍ

أَنَّ النَّبِيَّ ﷺ احْتَجَمَ وَهُوَ مُحْرِمٌ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ وَعَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ وَجَابِرٍ  

قَالَ أَبُو عِيسَى حَدِيثُ ابْنِ عَبَّاسٍ حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدْ رَخَّصَ قَوْمٌ مِنْ أَهْلِ الْعِلْمِ فِي الْحِجَامَةِ لِلْمُحْرِمِ وَقَالُوا لاَ يَحْلِقُ شَعَرًا وَقَالَ مَالِكٌ لاَ يَحْتَجِمُ الْمُحْرِمُ إِلاَّ مِنْ ضَرُورَةٍ وَقَالَ سُفْيَانُ الثَّوْرِيُّ وَالشَّافِعِيُّ لاَ بَأْسَ أَنْ يَحْتَجِمَ الْمُحْرِمُ وَلاَ يَنْزِعُ شَعَرًا
