1. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ’Isma‘il from af-Fadf ibn Shadhan all from Hammad ibn ‘Isa from Hariz from Muhammad ibn Muslim who has said the following:

“I once asked one of the two Imam, ‘Alayhim al-Salam, about a man who performs Salah (prayer) in one shirt or a gown of a single layer or stuffed (of several layers), one without a loincloth. He (the Imam) said, ‘If one is wearing a shirt which is of a densely woven fabric or a gown which does not have a long opening (on its sides), then it is not an offense to use them in Salah (prayer). Or if it is one piece of fabric which is placed on the right shoulder and then one end sent under the left arm and turned back over the shoulder and so on or a pant (pajama) in which case one is to secure it with something like even a piece of rope to one’s shoulders.’”
