Sunan Ibn Majah, Book 25, Hadith 3231 (In-Book) ⓘ
It was narrated from Ibn ‘Umar that the Messenger of Allah said: ‘Whoever among you can die in Al-Madinah, let him do so, for I will bear witness in favor of those who die there.”
حَدَّثَنَا بَكْرُ بْنُ خَلَفٍ، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنَا أَبِي، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ مَنِ اسْتَطَاعَ مِنْكُمْ أَنْ يَمُوتَ بِالْمَدِينَةِ فَلْيَفْعَلْ فَإِنِّي أَشْهَدُ لِمَنْ مَاتَ بِهَا " .
