Tafsir of Al-Ma'aarij 70:42

فذرهم

So leave them, meaning, `O Muhammad!'

يخوضوا ويلعبوا

to plunge in vain talk and play about, meaning, leave them in their denial, disbelief and obstinance.

حتى يﻼقوا يومهم الذي يوعدون

until they meet their Day which they are promised. meaning, they are going to know the outcome of that and taste its evil consequences

يوم يخرجون من اﻻجداث سراعا كٲنهم إلى نصب يوفضون
