Surah 70

Surah 70:42

"So leave them! Let them banter and jest, until they meet their Day which they are promised,"

70.42 – So leave them! Let them banter and jest, until they meet their Day
The sūra directly addresses the messenger encouraging him to leave it to Allah to deal with the disbelievers and to be patient (see v. 5). The reckoning will come on the Day of Resurrection (v. 43).
