[Machine] The Messenger of Allah ﷺ said, "The lifespan of Islam is based on thirty-five or thirty-six years. If they are destroyed, then the way of those who perished remains as a guidance. But if their religion remains, it will last for seventy years." Umar asked, "O Messenger of Allah, by what is left or what has passed?" He replied, "By what is left."
قَالَ رَسُولُ اللَّهِ ﷺ «تَدُورُ رَحَى الْإِسْلَامِ عَلَى خَمْسٍ وَثَلَاثِينَ أَوْ سِتٍّ وَثَلَاثِينَ فَإِنْ يَهْلِكُوا فَسَبِيلُ مَنْ هَلَكَ وَإِنْ بَقِيَ لَهُمْ دِينُهُمْ فَسَبْعِينَ عَامًا» قَالَ عُمَرُ يَا رَسُولَ اللَّهِ بِمَا بَقِيَ أَوْ بِمَا مَضَى؟ قَالَ «بِمَا بَقِيَ»
