Ibn 'Umar (RAA) narrated, ‘The Messenger of Allah was asked about what the person who is in a state of Ihram (Muhrim) should wear. He answered, "A person in the state of Ihram. is not allowed to wear a sewn shirt, a turban, trousers, a hooded robe, shoes or sewn slippers (Khuff), unless one is unable to find unsown slippers, then he may wear his Khuff or shoes provided one cuts them below the ankles, and you must not wear clothing that has been dyed with sweet smelling fragrance (such as saffron).” Agreed upon, and the wording is from Muslim.

وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا: { أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-سُئِلَ: مَا يَلْبَسُ اَلْمُحْرِمُ مِنْ اَلثِّيَابِ? فَقَالَ: " لَا تَلْبَسُوا الْقُمُصَ, وَلَا اَلْعَمَائِمَ, وَلَا السَّرَاوِيلَاتِ, وَلَا اَلْبَرَانِسَ, وَلَا اَلْخِفَافَ, إِلَّا أَحَدٌ لَا يَجِدُ اَلنَّعْلَيْنِ فَلْيَلْبَسْ اَلْخُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ اَلْكَعْبَيْنِ, وَلَا تَلْبَسُوا شَيْئًا مِنْ اَلثِّيَابِ مَسَّهُ اَلزَّعْفَرَانُ وَلَا اَلْوَرْسُ" } مُتَّفَقٌ عَلَيْهِ وَاللَّفْظُ لِمُسْلِمٍ 1‏.‏ ‏1 ‏- صحيح.‏ رواه البخاري ( 1542 )‏، ومسلم ( 1177 )‏.‏
