Surah 31. Luqman, Ayah 33

For instance, the self-deluding expectation, while deliberately committing a sin, that God will forgive it (sa'id ibn Jubayr, as quoted by Tabari, Baghawi, Zamakhshari). According to Tabari, the term gharur denotes "anything that deludes" (ma gharra) a person in the moral sense, whether it be Satan, or another human being, or an abstract concept, or (as in 57:14 ) "wishful thinking".

 Satan.

On the Day of Reckoning no one can help another. The most loving father cannot help his son or be a substitute for him, and vice versa. Each will have his own personal responsibilities.

The Chief Deceiver is Satan. It may make us forget that Time is fleeting and delude us by suggesting that the Reckoning may not come, whereas it is certain to come, because Allah's promise is true. We must not play with Time nor be deceived by appearances. The Day may come to-day or to-morrow or when we least expect it.
