[Machine] We used to wear clothes that we hadn't washed, and we would wear the garment called "al-mumashshaq," which is only a lining. 'Ikrimah, the freed slave of Ibn 'Abbas, narrated that the Prophet ﷺ changed his clothes with "at-tan'aim," while he was in a state of Ihram. Abu Dawud included this narration in his book "Al-Marasi."  

كُنَّا نَلْبَسُ مِنَ الثِّيَابِ إِذَا أَهْلَلْنَا مَا لَمْ نُهِلَّ فِيهِ وَنَلْبَسُ الْمُمَشَّقَ إِنَّمَا هُوَ بَطِينٌ وَرُوِّينَا عَنْ عِكْرِمَةَ مَوْلَى ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ ﷺ غَيَّرَ ثَوْبَيْهِ بِالتَّنْعِيمِ وَهُوَ مُحْرِمٌ أَوْرَدَهُ أَبُو دَاوُدَ فِي الْمَرَاسِيلِ
