Sahih Muslim Book - 15, Hadith - 3352

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا عَبْدُ الْعَزِيزِ - يَعْنِى الدَّرَاوَرْدِىَّ - عَنِ الْعَلاَءِ عَنْ أَبِيهِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « يَأْتِى عَلَى النَّاسِ زَمَانٌ يَدْعُو الرَّجُلُ ابْنَ عَمِّهِ وَقَرِيبَهُ هَلُمَّ إِلَى الرَّخَاءِ هَلُمَّ إِلَى الرَّخَاءِ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ وَالَّذِى نَفْسِى بِيَدِهِ لاَ يَخْرُجُ مِنْهُمْ أَحَدٌ رَغْبَةً عَنْهَا إِلاَّ أَخْلَفَ اللَّهُ فِيهَا خَيْرًا مِنْهُ أَلاَ إِنَّ الْمَدِينَةَ كَالْكِيرِ تُخْرِجُ الْخَبِيثَ. لاَ تَقُومُ السَّاعَةُ حَتَّى تَنْفِىَ الْمَدِينَةُ شِرَارَهَا كَمَا يَنْفِى الْكِيرُ خَبَثَ الْحَدِيدِ ».

It was narrated from Abu Hurairah that the Messenger of Allah (S.A.W) said: “There will come a time when a man will call his paternal cousin and his relative, saying: ‘Come to a life of ease, come to a life of ease,” but Al-Madinah is better for them, if only they knew. By the One in Whose Hand is my soul, no one of them departs out of dislike for it, but Allah will replace him therein with one who is better than him. Verily Al-Madinah is like a bellows: It eliminates dross. The Hour will not begin until Al-Madinah eliminates its evil ones as the bellows eliminate the impurities of iron.”
