وَيَسۡتَعۡجِلُونَكَ بِٱلۡعَذَابِ وَلَن يُخۡلِفَ ٱللَّهُ وَعۡدَهُۥۚ وَإِنَّ يَوۡمًا عِندَ رَبِّكَ كَأَلۡفِ سَنَةٖ مِّمَّا تَعُدُّونَ ٤٧
And they urge you to hasten the punishment. But Allāh will never fail in His promise. And indeed, a day with your Lord is like a thousand years of those which you count.
Translation: Saheeh International (English)
Each word's meaning and sound
O Messenger, the disbelievers amongst your people seek quick punishment in this world and deferred punishment in the Hearafter, when they were warned of them. Allah will never break the promise of it He has made to them. Amongst the quick punishment is what befell them on the day of Badr. And one day of punishment in the afterlife is like a thousand years of what you count in worldly years, due to the punishment it contains.
