The Messenger of Allah ﷺ said, "Islam began as something strange, and it will return to being strange as it began, so blessed are the strangers."
قال رسول الله ﷺ: بدأ الإسلام غريبا وسيعود كما بدأ غريبا، فطوبى للغرباء.
Muslim narrated it in the Book of Faith (145) through multiple routes from Marwan Fazari, from Yazid bin Kaysan, from Abu Hazim, from Abu Hurairah, who mentioned it.
