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. ") (Using translation from Bukhārī 365)
قَامَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَسَأَلَهُ عَنِ الصَّلَاةِ فِي الثَّوْبِ الْوَاحِدِ فَقَالَ أَوَ كُلُّكُمْ يَجِدُ ثَوْبَيْنِ ثُمَّ قَامَ رَجُلٌ إِلَى عُمَرَ فَسَأَلَهُ عَنِ الصَّلَاةِ فِي الثَّوْبِ الْوَاحِدِ فَقَالَ إِذَا وَسَّعَ اللهُ 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 وَأَحْسِبُهُ قَالَ فِي تُبَّانٍ وَرِدَاءٍ
