رَبَّنَا أَتْمِمْ لَنَا نُورَنَا وَاغْفِرْ لَنَا إِنَّكَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ
Rabbanaa atmim lanaa nuuranaa wagh-fir lanaa, innaka ‘alaa kulli shay’in qadiir. (66:8)
Our Lord, perfect our light for us, and forgive us. Surely you have power over all things.
This will be the du’aa of the Prophet (sallallahu alayhi wa sallem) and the believers on the Day of Resurrection, when “Allah will not disgrace the Prophet (sallallahu alayhi wa sallem) and the believers with him” (At-Tahrim, 66:8). A report from Sayyidna Abu Umamah (ra) gives details of distribution of light in the Hereafter. Keeping it in mind will help us understand the importance of this du’aa. It states:
Then you will be transferred from the graves to the Plain of Gathering where there will be different stages and spots to stand or wait. Then there will come a stage when some faces will brighten up and others will be darkened by the Divine command. An intense darkness will prevail and nobody will be able to see anything. Thereafter light will be distributed.
Another report of Ibn Abi Hatim, quoted by Ibn Kathir, narrates of the authority of Sayyidna ‘Abdullah ibn Mas’ud (ra):
Each believer will receive the light commensurate with his deeds. Some will have light as large as a mountain, some as a date tree, some as big as the height of a man. The lease among them will have a light as big as his index finger; it will light at times and extinguish at other times.
The hypocrites and the disbelievers will not receive any light.
The crossing of the Bridge will take place afterwards and those without light will not be able to cross it safely (Ma’ariful al-Qur’an).
