Tafsir of Al-Mursalat 77:15

Surah Al-Mursalat (77): Verse 15

{وَيْلٌ يَوْمَئِذٍ لِلْمُكَذِّبِينَ}

This refers to those who deny Monotheism (Tawhid), Prophethood (Nubuwwah), the Resurrection (Ma'ad), and everything reported by the Prophets, peace be upon them.

Two questions remain here:

Answer: Originally, Wail (Woe) is an accusative verbal noun (masdar mansub) standing in place of its verb. However, it has been shifted to the nominative case (raising/raf') to indicate the permanence and continuity of the doom upon the one being addressed. Similar examples include {سَلَامٌ عَلَيْكُمْ} (Peace be upon you). It is permissible for it to be read with the accusative (Waylan), but this reading is not attested.

Answer: This is addressed in two ways:

1. Interpretation 1 (Weak): The implied meaning is: "What you are promised is certainly going to happen when the stars are extinguished." This is considered weak because it places the condition within the context of the promise itself.
2. Interpretation 2 (Stronger): The response is omitted (mahthuf). The implied structure is: "When the stars are extinguished, and when [other signs occur], then the recompense for deeds will take place, and the Resurrection will commence."

{أَلَمْ نُهْلِكِ الْأَوَّلِينَ * ثُمَّ نُتْبِعُهُمُ الْآخِرِينَ * كَذَلِكَ نَفْعَلُ بِالْمُجْرِمِينَ * وَيْلٌ يَوْمَئِذٍ لِلْمُكَذِّبِينَ}
