«إن أقواما بالمدينة خلفنا ما سلكنا شعبا ولا واديا إلا وهم معنا حبسهم العذر»
The Prophet (peace and blessings be upon him) said:
"Indeed, there are some people in Madinah who have stayed behind us, yet we do not pass through any mountain pass or valley except that they are with us (in reward); only a (legitimate) excuse has held them back there."
