Du'a on completing the Qur'an: O Allah, do not leave for us any sin

اللَّهُمَّ لَا تَدَعْ لَنَا ذَنْبًا إِلَّا غَفَرْتَهُ، وَلَا هَمًّا إِلَّا فَرَّجْتَهُ، وَلَا دَيْنًا إِلَّا قَضَيْتَهُ، وَلَا حَاجَةً مِنْ حَوَائِجِ الدُّنْيَا وَالْآخِرَةِ إِلَّا قَضَيْتَهَا يَا أَرْحَمَ الرَّاحِمِينَ

Allahumma la tada' lana dhanban illa ghafartah, wa la hamman illa farrajtah, wa la daynan illa qadaytah, wa la hajatan min hawa'ijid-dunya wal-akhirati illa qadaytaha ya arhamar-rahimin

O Allah, do not leave for us any sin but that You forgive it, nor any distress but that You relieve it, nor any debt but that You pay it, nor any need of this world and the Hereafter but that You fulfil it, O Most Merciful of those who show mercy.

Adapted from Jāmiʿ al-Tirmidhī 479, which reads "لَا تَدَعْ لِي ذَنْبًا إِلَّا غَفَرْتَهُ وَلَا هَمَّا إِلَّا فَرَّجْتَهُ وَلَا حَاجَةً هِيَ لَكَ رِضًا إِلَّا قَضَيْتَهَا يَا أَرْحَمَ الرَّاحِمِينَ" (Do not leave me a sin but that You forgive it, nor a worry but that You relieve it, nor a need that pleases You but that You fulfil it, O Most Merciful of the merciful). This version says "us" instead of "me", adds "nor any debt but that You settle it", and widens the last request.
