A man stood up and asked the Prophet ﷺ about praying in a single garment. The Prophet ﷺ said, "Has every one of you two garments?" A man put a similar question to ʿUmar on which he replied, "When Allah makes you wealthier then you should clothe yourself properly during prayers. Otherwise one can pray with an Izar and a Rida' (a sheet covering the upper part of the body.) Izar and a shirt, Izar and a Qaba', trousers and a Rida, trousers and a shirt or trousers and a Qaba', Tubban and a Qaba' or Tubban and a shirt." (The narrator added, "I think that he also said a Tubban and a Rida. ")  

قَامَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَسَأَلَهُ عَنِ الصَّلاَةِ فِي الثَّوْبِ الْوَاحِدِ فَقَالَ أَوَكُلُّكُمْ يَجِدُ ثَوْبَيْنِ ثُمَّ سَأَلَ رَجُلٌ عُمَرَ فَقَالَ إِذَا وَسَّعَ اللَّهُ فَأَوْسِعُوا جَمَعَ رَجُلٌ عَلَيْهِ ثِيَابَهُ صَلَّى رَجُلٌ فِي إِزَارٍ وَرِدَاءٍ فِي إِزَارٍ وَقَمِيصٍ فِي إِزَارٍ وَقَبَاءٍ فِي سَرَاوِيلَ وَرِدَاءٍ فِي سَرَاوِيلَ وَقَمِيصٍ فِي سَرَاوِيلَ وَقَبَاءٍ فِي تُبَّانٍ وَقَبَاءٍ فِي تُبَّانٍ وَقَمِيصٍ قَالَ وَأَحْسِبُهُ قَالَ فِي تُبَّانٍ وَرِدَاءٍ  

A person asked Messenger of Allah ﷺ, "What should a Muhrim wear?" He replied, "He should not wear shirts, trousers, a burnus (a hooded cloak), or clothes which are stained with saffron or Wars (a kind of perfume). Whoever does not find a sandal to wear can wear Khuffs (socks made from thick fabric or leather), but these should be cut short so as not to cover the ankles.  

سَأَلَ رَجُلٌ رَسُولَ اللَّهِ ﷺ فَقَالَ مَا يَلْبَسُ الْمُحْرِمُ فَقَالَ لاَ يَلْبَسُ الْقَمِيصَ وَلاَ السَّرَاوِيلَ وَلاَ الْبُرْنُسَ وَلاَ ثَوْبًا مَسَّهُ الزَّعْفَرَانُ وَلاَ وَرْسٌ فَمَنْ لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا حَتَّى يَكُونَا أَسْفَلَ مِنَ الْكَعْبَيْنِ وَعَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ مِثْلَهُ
