Then after him We sent (many) messengers to their peoples: they brought them Clear Signs, but they would not believe what they had already rejected beforehand. Thus do We seal the hearts of the transgressors. Yunus 10:74 ⧉
Tafsir:
In this verse ‘transgressors’ refers to those who, once having rejected the Truth, stick to that position, make it a prestige issue and then go on continuously ignoring the Truth so that their religious knowledge and their being on the right path do not become doubtful in others’ eyes. Those who display this sort of behaviour are punished in this world by having their hearts sealed, that is, under the law of God, their psychology becomes gradually affected and finally they lose their sensitivity to the matter of Truth. The little sensitivity which they had earlier is ultimately benumbed. They do not remain capable of being anxious about Truth and untruth, or accepting the Truth rather than untruth. The history of Noah and the succeeding prophets bears testimony to this. The condition of any preacher of Truth who comes forward on behalf of God is such that he is not surrounded by outward worldly glories. The only strength he possesses is the power of reasoning. Those who are capable of recognising Truth in the language of reason are the only ones who acknowledge the preacher of Truth. Those whom the language of argument cannot influence are incapable of accepting or supporting the preacher of Truth.
