«تدور رحى الإسلام لخمس وثلاثين أوست وثلاثين أوسبع وثلاثين فإن يهلكوا فسبيل من هلك وإن يقم لهم دينهم يقم لهم سبعين عاما بما مضى»
The Prophet (peace and blessings be upon him) said:
"The mill of Islam will keep turning for thirty-five, thirty-six or thirty-seven years. If they perish, then it is the path of those who perished; and if their religion remains established for them, it will remain established for seventy years, including the time that has already passed."
