The Messenger of Allah ﷺ prohibited us to pray in a sheet of cloth without crossing both its ends, and he also prohibited us to pray in a wrapper without putting on a sheet.
نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُصَلَّى فِي لِحَافٍ لاَ يَتَوَشَّحُ بِهِ وَالآخَرُ أَنْ يُصَلَّى فِي سَرَاوِيلَ وَلَيْسَ عَلَيْكَ رِدَاءٌ
