If The Qamis Is Tight, He Should Wrap It Around His Lower Body

‘Ubadah b. al-Samit said:
we came to Jabir b. ‘Abd Allah. He said : I (Jabir) accompanied the Messenger of Allah ﷺ in a battle. He got up to pray. I had a sheet of cloth upon me, and I began to cross both the ends, but they did not reach (my shoulders). It had fringes which I turned over and crossed the two ends, and bowed down retaining it with my neck lest it should fall down. Then I came and stood on the left side of the Messenger of Allah ﷺ. He then took and brought me around him and set me on his right side. Then Ibn Sakhr came and stood on his left side. he then took us with his both hands and made us stand behind him. The Messenger of Allah ﷺ began to look at me furtive glances, but I could not understand. When I understood, he hinted at me tie the wrapper. When the Messenger of Allah ﷺ finished the prayer, he said (to me): O Jabir. I said; Yes, Messenger of Allah. He said; if it (the sheet) is wide, cross both its ends (over the shoulders); if it is tight, tie it over your loins.
