FELLOW FEELINGS H H 5 "We (the Companions) were returning from the battle of Tabuk with the Messenger of Allah, praise and peace be upon him, when he said: 'There are people left behind in Medina who were with us in every pass we crossed and every valley we traversed. They were held back by some (valid) excuse.'" R 5 Bukhari with a chain up to Anas said this.
4- ورواهُ البخاريُّ عن أنسٍ رضي الله عنه ، قَالَ : رَجَعْنَا مِنْ غَزْوَةِ تَبُوكَ مَعَ النَّبيِّ صلى الله عليه وآله وسلم ، فقال : "إنَّ أقْواماً خَلْفَنَا بالْمَدِينَةِ مَا سَلَكْنَا شِعْباً وَلاَ وَادياً ، إلاّ وَهُمْ مَعَنَا ؛ حَبَسَهُمُ العُذْرُ" .
