Du'a on completing the Qur'an: Our Lord! Give unto us in the world

رَبَّنَآ ءَاتِنَا فِي ٱلدُّنۡيَا حَسَنَةࣰ وَفِي ٱلۡأٓخِرَةِ حَسَنَةࣰ وَقِنَا عَذَابَ ٱلنَّارِ وَصَلَّى اللَّهُ عَلَى سَيِّدِنَا وَنَبِيِّنَا مُحَمَّدٍ وَعَلَى آلِهِ وَأَصْحَابِهِ الْأَخْيَارِ وَسَلَّمَ تَسْلِيمًا كَثِيرًا

Rabbana atina fid-dunya hasanatan wa fil-akhirati hasanatan wa qina 'adhaban-nar, wa sallallahu 'ala sayyidina wa nabiyyina Muhammad, wa 'ala alihi wa ashabihil-akhyar, wa sallama tasliman kathira

Our Lord! Give unto us in the world that which is good and in the Hereafter that which is good, and guard us from the doom of Fire. And may Allah send blessings upon our master and prophet Muhammad, and upon his family and his righteous companions, and grant them abundant peace.

Qur'an 2:201, followed by a salawat (a blessing on the Prophet, peace be upon him) that is not a narration from the Prophet (peace be upon him).
