Sahih Muslim , Book 15, Hadith 551 (In-Book) ⓘ
Abu Huraira (Allah be pleased with him) reported the Messenger of Allah as saying: For one among my Ummah who shows endurance against the hardships and rigours of Medina, I would be an intercessor or a witness on his behalf on the Day of Resurrection.
وَحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ جَمِيعًا عَنْ إِسْمَاعِيلَ بْنِ جَعْفَرٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَصْبِرُ عَلَى لأْوَاءِ الْمَدِينَةِ وَشِدَّتِهَا أَحَدٌ مِنْ أُمَّتِي إِلاَّ كُنْتُ لَهُ شَفِيعًا يَوْمَ الْقِيَامَةِ أَوْ شَهِيدًا " .
