It has been narrated on the authority of Sahl b. Sa'd as-Sa'idi that the Messenger of Allah ﷺ said: The journey undertaken by a person in the morning (for Jihad) in the way of Allah (will merit a reward) better than the world and all that is in it.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنْ أَبِيهِ، عَنْ سَهْلِ،
بْنِ سَعْدٍ السَّاعِدِيِّ عَنْ رَسُولِ اللَّهِ ﷺ قَالَ
" وَالْغَدْوَةَ يَغْدُوهَا الْعَبْدُ
فِي سَبِيلِ اللَّهِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا " .
