الترمذي:٨٣٠حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي زِيَادٍ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَعْقُوبَ الْمَدَنِيُّ عَنِ ابْنِ أَبِي الزِّنَادِ عَنْ أَبِيهِ عَنْ خَارِجَةَ بْنِ زَيْدِ بْنِ ثَابِتٍ عَنْ أَبِيهِ

أَنَّهُ رَأَى النَّبِيَّ ﷺ تَجَرَّدَ لإِهْلاَلِهِ وَاغْتَسَلَ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ وَقَدِ اسْتَحَبَّ قَوْمٌ مِنْ أَهْلِ الْعِلْمِ الاِغْتِسَالَ عِنْدَ الإِحْرَامِ وَبِهِ يَقُولُ الشَّافِعِيُّ
