Where to Place Your Shoes When You Take Them off for Prayer
by The Albaani Site
Al-Albaani said, “And when he takes his sandals off he should not put them on his right side but on the left [instead], if there is no one praying to his left, if there is then he places them between his feet …”
“And when he ﷺ would take them off he would place them on his left, and he would say, ‘When any of you prays, he should not place his sandals on his right side or on his left so as to be on the right side of someone else, unless no one is on his left, but he should place them between his feet.’”
