Muwatta Malik 320
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ سَائِلاً، سَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الصَّلاَةِ فِي ثَوْبٍ وَاحِدٍ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" أَوَلِكُلِّكُمْ ثَوْبَانِ "
Yahya related to me from Malik from Ibn Shihab from Said ibn al- Musayyab from Abu Hurayra that some one asked the Messenger of Allah, may Allah bless him and grant him peace about praying in one garment. The Messenger of Allah, may Allah bless him and grant him peace, said, "Do you all have two garments?"
