The Prophet ﷺ said, "In Paradise there is a tree which is so big that a rider can travel in its shade for one hundred years without passing it; and if you wish, you can recite: 'In shade long extended.' 56.30. (Using translation from Bukhārī 4881)
وَقَالَ ﷺ إِنَّ فِي الْجَنَّةِ شَجَرَةً يَسِيرُ الرَّاكِبُ فِي ظِلِّهَا مِائَةَ عَامٍ لَا يَقْطَعُهَا فَاقْرَءُوا إِنْ شِئْتُمْ {وَظِلٍّ مَمْدُودٍ}[الواقعة 30]
