﴿ فَضْلًۭا مِّن رَّبِّكَ ۚ ذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ ﴾

“an act of thy Sustainer’s favour: and that, that will be the triumph supreme!”

(A bounty from thy Lord) a favour from your Lord; and it is also said this means: a gift from your Lord. (That) gift (is the Supreme Triumph) the supreme safety: they earned the Garden and became safe from the Fire.
