قَالَ رَسُولُ اللهِ ﷺ: «مَنْ قَالَ: سُبْحَانَ اللهِ العَظِيمِ وَ بِحَمْدِهِ، غُرِسَتْ لَهُ نَخْلَةٌ فِي الجَنَّةِ»

“Whoever says: ‘How perfect Allāh is, The Supreme, and I praise Him,’ a palm tree is planted for him in paradise.”

Reference: “Whoever says: ‘How perfect Allāh is, The Supreme, and I praise Him,’ a palm tree is planted for him in paradise.” Al-Tirmidhī (#3464--3465, 5/511), al-Hākim (1/501) and he authenticated it and al-Dhahabī agreed with him. Also see _Ṣaḥīḥ al-Jāmiʿ_ (#6429, 5/531) and _Ṣaḥīḥ al-Tirmidhī_ (3/160).
