[Machine] The Messenger of Allah ﷺ said, "Islam will be disintegrated piece by piece, just as a rope is untied strength by strength."  

أحمد:١٨٠٣٩ – حَدَّثَنَا هَيْثَمُ بْنُ خَارِجَةَ أَخْبَرَنَا ضَمْرَةُ عَنْ يَحْيَى بْنِ أَبِي عَمْرٍو عَنِ ابْنِ فَيْرُوزَ الدَّيْلَمِيِّ عَنْ أَبِيهِ قَالَ

قَالَ رَسُولُ اللهِ ﷺ لَيُنْقَضَنَّ الْإِسْلَامُ عُرْوَةًعُرْوَةً كَمَا يُنْقَضُ الْحَبْلُ قُوَّةً قُوَّةً
