It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The mill of Islam will keep turning for thirty-five (35), thirty-six (36), or thirty-seven (37) years. After that, if the Muslims are destroyed, they will follow the path of those who were destroyed, and if they remain, their religion will remain for seventy years."
