Rabbana atmim lana nurana
A prayer for complete light and forgiveness on the Day believers will need both. It asks Allah (SWT) to carry faith to its good completion, not merely to give a promising beginning.
Recite it when asking for steadiness in faith, forgiveness, a good end, and light in the Hereafter. It is also fitting when you fear losing momentum after beginning something good. No fixed count is prescribed.
The Arabic and meaning are paired with Quran 66:8. No special promise or count is added without a cited basis.
Rabbana atmim lana nurana wa-ghfir lana, innaka 'ala kulli shay'in qadir.
Our Lord, perfect for us our light and forgive us. Indeed, You are over all things competent.
The verse calls believers to sincere repentance, then shows them asking for their light to be perfected and their sins forgiven. The prayer ties hope to tawbah and perseverance.
A good beginning is a gift, but completion is also a gift. These words teach the heart to ask Allah (SWT) to preserve guidance until it reaches its full result.
