Translation:

200. Thus have We caused it to enter the hearts of the Sinners.

Notes (Tafseer)

3229. "Thus" I think means through the medium of the Arabic language and the Arab people. The Qur-an penetrated through their language and their hearts. If the hard-hearted among them did not believe, they will see when the Penalty comes, how grievous a mistake they made. For the Penalty must come; even when they least expected it. They will be caught saying or thinking, "There is plenty of time; we can get another respite," when already it will have become too late for them to turn over a new leaf.
