Even the reprieve has a fixed end date.
The Day of the time well-known
Iblis asked until the resurrection. Allah answers until the Day of the time well-known. The date is set by Allah, not by Iblis. For a Prophet ﷺ tired of mockery in Makkah, this said: the opposition has an end.
You keep slipping on the same thing, over and over. Or someone keeps hurting you and it feels endless. Every whisper and every harm runs on a clock Allah set. It does not get the last word.
This struggle will never end.
Even Iblis has a deadline; the pull toward wrong runs out on a day Allah has fixed.
When the familiar urge comes today, remind yourself: this has an end, and say a'udhu billah.
