Sahih al-Bukhari 6415Book 81, Hadith 4
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنْ أَبِيهِ، عَنْ سَهْلٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " مَوْضِعُ سَوْطٍ فِي الْجَنَّةِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا، وَلَغَدْوَةٌ فِي سَبِيلِ اللَّهِ أَوْ رَوْحَةٌ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا ".
I heard the Prophet (ﷺ) saying, "A (small) place equal to an area occupied by a whip in Paradise is better than the (whole) world and whatever is in it; and an undertaking (journey) in the forenoon or in the afternoon for Allah's Cause, is better than the whole world and whatever is in it."
