Narrated Sahl bin Sa`d Al-Saidi: Allah's Messenger said, "A place in Paradise equal to the size of a lash is better than the whole world and whatever is in it."
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَوْضِعُ سَوْطٍ فِي الْجَنَّةِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا " .
