The Prophet ﷺ said, "When one of you prays in a single garment, let him cross its two ends over his shoulders."
حدثنا يزيد بن هارون أخبرنا هشام عن يحيى عن عكرمة
عن النبي ﷺ قال إذا صلى أحدكم في ثوب واحد فليخالف بين طرفيه على عاتقيه
Its isnad is sahih. Abu Dawud reported it, 627 [1:241 Awn al-Mabud], from the route of Hisham, who is Ibn Abu Kathir, from Yahya, who is Ibn Abu Kathir, with this isnad.Bukhari reported it, 1:398, from the route of Shayban, from Yahya, with it, similarly. Something similar in meaning has already passed from another route, 7305.As for his words, "let him cross its two ends over his shoulders," Khattabi said in al-Maalim, 598, he means that one does not wrap it around his waist and tie its ends around his hips, but rather wraps it around himself and raises its ends, crossing them over each other, and ties it over his shoulders, so that it becomes like a lower garment and an upper garment combined.
