بِسْمِ اللهِ الرَّحْمَٰنِ الرَّحِيمِ
أَلْهَاكُمُ التَّكَاثُرُ ١
Competing with each other to boast about having more wealth [or] children distracted you from obeying Allāh.
حَتَّىٰ زُرْتُمُ الْمَقَابِرَ ٢
And you continued to be distracted by that until you ended up at the graves and were buried among them.
كَلَّا سَوْفَ تَعْلَمُونَ ٣
Competing with others over wealth should never distract you in this way. You will come to know with clarity that a [good] place in the Hereafter is better for you.
ثُمَّ كَلَّا سَوْفَ تَعْلَمُونَ ٤
Again then, be on alert: you will come to know the horrible outcome of your having been distracted from [working towards a good place in the Hereafter].
كَلَّا لَوْ تَعْلَمُونَ عِلْمَ الْيَقِينِ ٥
Competing with others over wealth should never distract you in this way. If you knew, really knew, you would have definitely refrained, having been put in check, and definitely rushed to save yourselves from destruction.
لَتَرَوُنَّ الْجَحِيمَ ٦
[By Allāh,] you will most definitely see the Blazing Hot Fire.
ثُمَّ لَتَرَوُنَّهَا عَيْنَ الْيَقِينِ ٧
Again then, [by Allāh,] you will most definitely see it without harboring a doubt.
ثُمَّ لَتُسْأَلُنَّ يَوْمَئِذٍ عَنِ النَّعِيمِ ٨
Again then, [by Allāh,] you will most definitely be questioned on the Day of Resurrection about every kind of good thing [you] enjoyed in life.
