They sold Allah's signs for a small price.
Trading the truth for a little gain
Ibn Kathir explains that the idolaters gave up following Allah's signs for the lower affairs of this life and then tried to keep the believers from the truth as well. Losing guidance yourself and blocking others from it were joined.
The promotion that needs a small lie. Skipping prayer for one more hour of overtime. Laughing along when religion is mocked, to stay in the group. Every price paid for leaving the truth is small, compared to what you give away.
It is just this once, and what I get is worth it.
Anything I take in exchange for Allah's guidance is a small price.
Notice one small compromise you make for convenience. Skip it once today.
