The Messenger of Allah ﷺ said, "Between every two calls to prayer there is a prayer, between every two calls to prayer there is a prayer, between every two calls to prayer there is a prayer, for whoever wishes."
أخبرنا عبيد الله بن سعيد عن يحيى عن كهمس قال حدثنا عبد الله بن بريدة
قال رسول الله ﷺ بين كل أذانين صلاة بين كل أذانين صلاة بين كل أذانين صلاة لمن شاء
