Sahih al-Bukhari · Book 56: Fighting for the Cause of Allah (Jihaad) · To proceed in Allah's Cause
Narrated Anas bin Malik:
حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ ، حَدَّثَنَا وُهَيْبٌ ، حَدَّثَنَا حُمَيْدٌ ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لَغَدْوَةٌ فِي سَبِيلِ اللَّهِ أَوْ رَوْحَةٌ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا " .
The Prophet (ﷺ) said, "A single endeavor (of fighting) in Allah's Cause in the forenoon or in the afternoon is better than the world and whatever is in it."
