Dua #2.
رَبَّنَا لَا تَجْعَلْنَا فِتْنَةً لِّلَّذِينَ كَفَرُوا وَاغْفِرْ لَنَا رَبَّنَا إِنَّكَ أَنتَ الْعَزِيزُ الْحَكِيمُ
الممتحنة :5
Rabbana la taj'alna fitnatal lilladhina kafaru waghfir lana Rabbana innaka antal 'Azizul-Hakim
Our Lord! Make us not a (test and) trial for the Unbelievers, but forgive us, our Lord! for Thou art the Exalted in Might, the Wise. - 60:5
This is also part of the dua made by Ibrahim (A) and his followers. Mujahid (R.A) states that this ayah means: “Do not punish us through the hands of the kuffaar nor give us adhab (punishment) directly, otherwise the kuffaar will say that if these people were true believers, then no adhab would befall them”.
