Hadith 5580
He reported God's messenger as saying, "When the inhabitants of paradise enter paradise and the inhabitants of hell enter hell God most high will say, `Bring forth those in whose hearts there is as much faith as a grain of mustard-seed.' They will then be brought forth burned and turned to charcoal and be cast into the river of life, and they will sprout as does a seed in the rubbish carried away by a flood. Have you not seen that it comes out yellow and twisted?" (Bukhari and Muslim.)
وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " إِذَا دَخَلَ أَهْلُ الْجَنَّةِ الْجَنَّةَ وَأَهْلُ النَّارِ النَّارَ يَقُولُ اللَّهُ تَعَالَى: مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ مِنْ إِيمَانٍ فَأَخْرِجُوهُ فَيَخْرُجُونَ قَدِ امْتَحَشُوا وَعَادُوا حُمَمًا فَيُلْقَوْنَ فِي نَهْرِ الْحَيَاةِ فَيَنْبُتُونَ كَمَا تَنْبُتُ الْحِبَّةُ فِي حَمِيلِ السَّيْلِ أَلَمْ تَرَوْا أَنَّهَا تَخْرُجُ صَفْرَاءَ مُلْتَوِيَةً ". مُتَّفَقٌ عَلَيْهِ
