once
رَبَّنَا لَا تُزِغْ قُلُوبَنَا بَعْدَ إِذْ هَدَيْتَنَا وَهَبْ لَنَا مِن لَّدُنكَ رَحْمَةً إِنَّكَ أَنتَ الْوَهَّابُ رَبَّنَا إِنَّكَ جَامِعُ النَّاسِ لِيَوْمٍ لَّا رَيْبَ فِيهِ إِنَّ اللَّهَ لَا يُخْلِفُ الْمِيعَادَ
Meaning
«Our Lord, let not our hearts deviate after You have guided us and grant us from Yourself mercy. Indeed, You are the Bestower! Our Lord, surely You will gather the people for a Day about which there is no doubt. Indeed, Allāh does not fail in His promise»
