Sahih Muslim , Book 7, Hadith 3175 (USC-MSA) ⓘ

Abu Sa'id Maula al-Mahri reported that he came to Abu Sa'id al-Khudri during the nights (of the turmoil) of al-Barrah, and sought his advice about leaving Medina, and complained of the high prices prevailing therein and his large family, and informed him that he could not stand the hardships of Medina and its rugged surrounding. He said to him: Woe to you; I will not advise you to do it, for I heard Allah's Messenger as saying: No one will endure hardships of Medina without my being an intercessor or a witness on his behalf on the Day of Resurrectiar), if he is a Muslim.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي سَعِيدٍ، مَوْلَى الْمَهْرِيِّ أَنَّهُ جَاءَ أَبَا سَعِيدٍ الْخُدْرِيَّ لَيَالِيَ الْحَرَّةِ فَاسْتَشَارَهُ فِي الْجَلاَءِ مِنَ الْمَدِينَةِ وَشَكَا إِلَيْهِ أَسْعَارَهَا وَكَثْرَةَ عِيَالِهِ وَأَخْبَرَهُ أَنْ لاَ صَبْرَ لَهُ عَلَى جَهْدِ الْمَدِينَةِ وَلأْوَائِهَا ‏.‏ فَقَالَ لَهُ وَيْحَكَ لاَ آمُرُكَ بِذَلِكَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ لاَ يَصْبِرُ أَحَدٌ عَلَى لأْوَائِهَا فَيَمُوتَ إِلاَّ كُنْتُ لَهُ شَفِيعًا أَوْ شَهِيدًا يَوْمَ الْقِيَامَةِ إِذَا كَانَ مُسْلِمًا ‏" ‏ ‏.‏
