Sunan Ibn Majah
The Chapters on Jihad — Hadith #2499
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ حُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا رَجَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ غَزْوَةِ تَبُوكَ فَدَنَا مِنَ الْمَدِينَةِ قَالَ " إِنَّ بِالْمَدِينَةِ لَقَوْمًا مَا سِرْتُمْ مِنْ مَسِيرٍ وَلاَ قَطَعْتُمْ وَادِيًا إِلاَّ كَانُوا مَعَكُمْ فِيهِ " . قَالُوا يَا رَسُولَ اللَّهِ وَهُمْ بِالْمَدِينَةِ قَالَ " وَهُمْ بِالْمَدِينَةِ حَبَسَهُمُ الْعُذْرُ " .
“When the Messenger of Allah (ﷺ) was returning from the campaign of Tabuk, and had drawn close to Al-Madinah, he said: ‘In Al-Madinah there are people who, as you traveled and crossed valleys, were with you.’ They said: ‘O Messenger of Allah, even though they are in Al-Madinah?’ He said: ‘Even though they were in Al-Madinah. They were kept behind by (legitimate) excuses.’”
