Sahih al-Bukhari 3250
Sahih al-Bukhari · Book 59: Beginning of Creation · The characteristics of Paradise, and the fact that it has already been created
Narrated Sahl bin Sa`d Al-Saidi:
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 " .
Allah's Messenger (ﷺ) said, "A place in Paradise equal to the size of a lash is better than the whole world and whatever is in it."
