Sahih Muslim 1881
Sahih Muslim · Book 33: The Book on Government · The virtue of going out in the morning or the evening in the cause of Allah
It has been narrated on the authority of Sahl b. Sa'd as-Sa'idi that the Messenger of Allah (ﷺ) said:
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَزُهَيْرُ بْنُ حَرْبٍ ، قَالاَ حَدَّثَنَا وَكِيعٌ ، عَنْ سُفْيَانَ ، عَنْ أَبِي حَازِمٍ ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " غَدْوَةٌ أَوْ رَوْحَةٌ فِي سَبِيلِ اللَّهِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا " .
A journey undertaken in the morning or evening (fond Jihad) in the way of Allah (will merit a reward) better than the world and all that is in it.
