وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَكَانَ لِزَامًا وَأَجَلٌ مُّسَمًّى
Were it not for a prior decree of your Lord and a specified time, [their doom] would have attended [their guilt].
Agha Ali Puya Commentary
Commentary on Quran 20:129
[Pooya/Ali Commentary 20:129] Refer to the commentary of Yunus: 19 and Hud :11. Aqa Mahdi Puya says: In the light of verse 77 of Furqan this verse indicates that the respite is allowed by Allah to give a chance to the people to amend their behaviour, turn repentant to Allah, avoid evil and do good by constantly remembering Allah and invoking His mercy and forgiveness.
Ali Muhammad Fazil Chinoy Commentary
Commentary on Quran 20:129-135
The Prophet said, “Every age has one Divine Light to guide people and I am the Divine Light of this age and after me shall be Ali, and thereafter, several of his descent 11 representatives of God shall be. N.B. This is exactly what Jesus claimed for himself (Vide St. John 9:5), “As long as I am in the world, I am the light of the world.”
