Fath al-Rabbani

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings be upon him) say: “Indeed, Islam began as something strange, and soon it will return to being strange as it was in the beginning. So glad tidings to the strangers of that time, when corruption will have spread in the rest of the era. By the One in whose hand is the soul of Abu al-Qasim! Faith will seek refuge towards these two mosques just as a snake seeks refuge in its hole.”
