The Prophet ﷺ said, "There is a tree in Paradise (which is so big and huge that) if a rider travels in its shade for one hundred years, he would not be able to cross it." (Using translation from Bukhārī 3251)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ «إِنَّ فِي الْجَنَّةِ شَجَرَةً يَسِيرُ الرَّاكِبُ فِي ظِلِّهَا مِائَةَ سَنَةٍ»  

[Machine] The Quran descended all at once on the Night of Decree to the lowest heaven, and then it was gradually revealed over a period of years. This is what is meant by His saying, "So I swear by the positions of the stars" (Quran 56:75)  

نَزَلَ الْقُرْآنُ جَمِيعًا فِي لَيْلَةِ الْقَدْرِ إِلَى السَّمَاءِ الدُّنْيَا ثُمَّ فُصِّلَ فَنَزَلَ فِي السِّنِينَ فَذَلِكَ قَوْلُهُ {فَلَا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ} [الواقعة 75]  

that the Prophet ﷺ would recite: "Furuhun Wa Raihanun Wa Jannatu Na'im (56:89)" (Using translation from Tirmidhī 2938)   

كَانَ رَسُولُ اللهِ ﷺ يَقْرَأُ {فَرَوْحٌ وَرَيْحَانٌ وَجَنَّةُ نَعِيمٍ} [الواقعة 89]
