Praying in a Single Garment (Hadith No. 348)
Hadith no. 347 is a repeat. Read it here.
Volume 1, Book 8, Number 348:
Narrated Muhammad bin Al-Munkadir:
Once Jabir prayed with his Izar tied to his back while his clothes were Lying beside him on a wooden peg. Somebody asked him, “Do you offer your prayer in a single Izar?” He replied, “I did so to show it to a fool like you. Had anyone of us two garments in the life-time of the Prophet?”
Salah (prayer) can be offered in a single garment (izar/rida), provided the body parts that need to be covered (for men: shoulders, belly button till knees) are properly covered.
Women need to cover head to toe. Hands, feet and face may show.
