باب فَضْلِ الْمَدِينَةِ وَدُعَاءِ النَّبِيِّ صلى الله عليه وسلم فِيهَا بِالْبَرَكَةِ وَبَيَانِ تَحْرِيمِها وَتَحْرِيمِ صَيْدِهَا وَشَجَرِهَا وَبَيَانِ حُدُودِ حَرَمِهَا
Sahih Muslim 1363 b

'Amir b. Sa'd b. Abu Waqqas reported on the authority of his father (Allah be pleased with him) that Allah's Messenger (ﷺ) said, and then the (above-mentioned) hadith was narrated with this addition:

" None should nurse ill-will towards the people of Medina, or Allah will melt him in fire like the melting of lead or the dissolution of salt in water.
وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، حَدَّثَنَا عُثْمَانُ بْنُ حَكِيمٍ الأَنْصَارِيُّ، أَخْبَرَنِي عَامِرُ بْنُ سَعْدِ بْنِ أَبِي وَقَّاصٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏.‏ ثُمَّ ذَكَرَ مِثْلَ حَدِيثِ ابْنِ نُمَيْرٍ وَزَادَ فِي الْحَدِيثِ ‏ "‏ وَلاَ يُرِيدُ أَحَدٌ أَهْلَ الْمَدِينَةِ بِسُوءٍ إِلاَّ أَذَابَهُ اللَّهُ فِي النَّارِ ذَوْبَ الرَّصَاصِ أَوْ ذَوْبَ الْمِلْحِ فِي الْمَاءِ ‏"‏ ‏.‏
