al-Ṣaffāt

بَلْ جَآءَ بِالْحَقّ‌ِ وَصَدَّقَ الْمُرْسَلِينَ

إِنَّكُمْ لَذَآئِقُواْ الْعَذَابِ الأَلِيمِ

ومَا تُجْزَوْنَ إِلاَّ مَا كُنتُمْ تَعْمَلُونَ

37. “Nay: he has come with the Truth and verified the (former) messengers.”

38. “Verily you will taste the painful punishment, (too).”

39. “And you are not requited except (for) what you were doing.”

The teachings of all Divine prophets are the same, and all prophets invite to Unity and the Truth, and the Prophet of Islam (S) has verified them, too. In this verse, in order to negate these baseless words and to defend the rank of revelation and prophecy of the holy Prophet (S), the Qur’an adds:

But you, O blind-hearted people! And you, O’ aberrant and foul-mouthed ones! You will surely taste the painful chastisement of Allah, because the retribution of those who intentionally called the content of the Holy Qur’an poems, and considered the holy Prophet of Islam (S) mad is a painful punishment.

This verse implies that they should not imagine that Allah is taker of vengeance and He wants to take vengeance from them. It is not such, as the verse says:

In fact, it is the result of your own deeds that incarnates in front of you and remains with you and hurts you. Your retribution is that very deed of yours.
