“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.’”
Sunan Ibn Majah Book 24, Hadith 12
