BUKHARI 2892:
from Sahl b. Saʿd al-Sāʿidī —
Messenger of Allah ﷺ said, "To guard Muslims from infidels in Allah's Cause for one day is better than the world and whatever is on its surface, and a place in Paradise as small as that occupied by the whip of one of you is better than the world and whatever is on its surface; and a morning's or an evening's journey which a slave (person) travels in Allah's Cause is better than the world and whatever is on its surface."
البخاري ٢٨٩٢:
عن سهل بن سعد الساعدي —
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ رِبَاطُ يَوْمٍ فِي سَبِيلِ اللَّهِ خَيْرٌ مِنَ الدُّنْيَا وَمَا عَلَيْهَا وَمَوْضِعُ سَوْطِ أَحَدِكُمْ مِنَ الْجَنَّةِ خَيْرٌ مِنَ الدُّنْيَا وَمَا عَلَيْهَا وَالرَّوْحَةُ يَرُوحُهَا الْعَبْدُ فِي سَبِيلِ اللَّهِ أَوِ الْغَدْوَةُ خَيْرٌ مِنَ الدُّنْيَا وَمَا عَلَيْهَا
