Regarding The Concession Allowing That (Red)
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ النَّمَرِيُّ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَهُ شَعْرٌ يَبْلُغُ شَحْمَةَ أُذُنَيْهِ وَرَأَيْتُهُ فِي حُلَّةٍ حَمْرَاءَ لَمْ أَرَ شَيْئًا قَطُّ أَحْسَنَ مِنْهُ .
Narrated Al-Bara' bin 'Azib: The Messenger of Allah (ﷺ) had hair which reached the lobes of his ears, and I saw him wearing red robe. I did not see anything more beautiful than it.
