﴿ فَذَكِّرْ إِن نَّفَعَتِ ٱلذِّكْرَىٰ ﴾

“REMIND, THEN, [others of the truth, regardless of] whether this reminding [would seem to] be of use [or not]:”

So remind admonish by the Qur’ān in case the reminder should be of benefit to the one whom you might remind the one mentioned in the following verse ‘he who fears will be reminded’ in other words even if it might not be of benefit for it is of benefit to some but of no benefit to others.
