عَنْ سَهْلٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ قَالَ سُبْحَانَ اللَّهِ الْعَظِيمِ نُبِتَ لَهُ غَرْسٌ فِي الْجَنَّةِ
Sahl narrates from his father that the Messenger of Allah, peace and blessings be upon him, said: Whoever says "Subhan Allah al-Azeem," a tree will be planted for him in Paradise.
