(1) باب مَا يُبَاحُ لِلْمُحْرِمِ بِحَجٍّ أَوْ عُمْرَةٍ وَمَا لاَ يُبَاحُ وَبَيَانِ تَحْرِيمِ الطِّيبِ عَلَيْهِ
Salim reported on the authority of his father ('Abdullah b. 'Umar) that the Messenger of Allah (ﷺ) was asked what a Muhrim should wear, whereupon he said:
A Muhrim should not wear a shirt, or a turban, or a cap, or trousers, or a cloth touched with wars or with saffron, nor (should he wear) stockings, but in case he does not find shoes, but (before wearing stockings) be should trim them (in such a way) that these should become lower than the ankles.
