Supplication

رَبَّنَا لاَ تُؤَاخِذْنَا إِن نَّسِينَا أَوْ أَخْطَأْنَا رَبَّنَا وَلاَ تَحْمِلْ عَلَيْنَا إِصْرًا كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِن قَبْلِنَا رَبَّنَا وَلاَ تُحَمِّلْنَا مَا لاَ طَاقَةَ لَنَا بِهِ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا أَنتَ مَوْلاَنَا فَانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ

“…O our Lord, do not hold us responsible if we forget or make mistake. O our lord, do not lay on us a burden such as you laid on those before us. O our Lord, do not impose upon us that which we have not the strength (to bear). Pardon us, and forgive us, and have mercy on us. You are our lord-master, so help us against the unbelieving people.” (Sura al-Baqara, 2:286)
The right path (what to do and what not to do) has been clearly shown to man by Allah. These commandments are very easy to follow, not beyond our capacity, as the holy Prophet once said: “I have brought for you a very easy religion.”
Now man is responsible for what he does. If we make mistakes, by breaking laws of Allah, we must admit our mistakes and humbly and sincerely seek forgiveness of our merciful Lord, who not only forgives faults but helps us to overcome our enemies and the enemies of Allah; and in this way, keeps away from us hardships and sorrows that they (enemies) might bring if Allah does not stop them, in answer to our supplications.
Through this prayer we pray for the triumph of truth over falsehood and the suppression of satanic tendencies by godliness, and ask Allah not to inflict on us situations under which we may not be able to avoid wrongdoing. After acknowledging our limitations we undertake to work at our maximum capacity, hoping that through his mercy He will wipe clean all traces of errors and mistakes.
