Sunan Ibn Majah, Hadith 3115 ⓘ
It was narrated that ‘Abdullah bin Miknaf said: “I heard Anas bin Malik say: ‘The Messenger of Allah said: “Uhud is a mountain which loves us and we love it, and it stands at one of the gates of Paradise. And ‘Aer* stands at one of the gates of Hell.’”
حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا عَبْدَةُ، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ مِكْنَفٍ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ إِنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " إِنَّ أُحُدًا جَبَلٌ يُحِبُّنَا وَنُحِبُّهُ وَهُوَ عَلَى تُرْعَةٍ مِنْ تُرَعِ الْجَنَّةِ وَعَيْرٌ عَلَى تُرْعَةٍ مِنْ تُرَعِ النَّارِ " .
