200 Preface كَذٰلِكَ سَلَكناهُ في قُلوبِ المُجرِمينَYusuf AliThus have We caused it to enter the hearts of the Sinners.1“Thus” I think means through the medium of the Arabic language and the Arab people. The Qur-ān penetrated through their language and their hearts. If the hardhearted 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.
