صَحِيحُ مُسْلِمٍ
Sahih Muslim 1387 a
The Book of Pilgrimage
The prohibition of wishing ill towards the people of Al-Madinah, and that the one who wishes them ill will be caused to melt by Allah
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ عُمَرَ بْنِ نُبَيْهٍ، أَخْبَرَنِي دِينَارٌ الْقَرَّاظُ، قَالَ سَمِعْتُ سَعْدَ بْنَ أَبِي وَقَّاصٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَنْ أَرَادَ أَهْلَ الْمَدِينَةِ بِسُوءٍ أَذَابَهُ اللَّهُ كَمَا يَذُوبُ الْمِلْحُ فِي الْمَاءِ .
Sa'd b. Abu Waqqas reported Allah's Messenger (ﷺ) as saying: He who intends to do harm to the people of Medina, Allah would efface him just as water dissolves salt.
