﴿ ٱلَّذِينَ يَقُولُونَ رَبَّنَآ إِنَّنَآ ءَامَنَّا فَٱغْفِرْ لَنَا ذُنُوبَنَا وَقِنَا عَذَابَ ٱلنَّارِ ﴾

“those who say, "O our Sustainer! Behold, we believe [in Thee]; forgive us, then, our sins, and keep us safe from suffering through the fire" -:”

Those alladhīna is either an adjectival qualification of or a substitution for the previous alladhīna who say “O Our Lord we believe in You and in Your Prophet; so forgive us our sins and guard us from the chastisement of the Fire”.
