Sahih Muslim 1911aBook 33, Hadith 227
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي غَزَاةٍ فَقَالَ " إِنَّ بِالْمَدِينَةِ لَرِجَالاً مَا سِرْتُمْ مَسِيرًا وَلاَ قَطَعْتُمْ وَادِيًا إِلاَّ كَانُوا مَعَكُمْ حَبَسَهُمُ الْمَرَضُ " .
We were with the Prophet (ﷺ) on an expedition. He said: There are some people in Medina. They are with you whenever you cover a distance or cross a valley. They have been detained by illness.
