﴿ إِلَّا رَحْمَةًۭ مِّن رَّبِّكَ ۚ إِنَّ فَضْلَهُۥ كَانَ عَلَيْكَ كَبِيرًۭا ﴾
“[Thou art spared] only by thy Sustainer's grace: behold, His favour towards thee is great indeed!”
((It is naught) save mercy) blessing (from thy Lord) He preserved the Qur'an in your heart. (Lo! His kindness unto you) through granting you prophethood and Islam (was ever great) was tremendous indeed.
