Dua before Salam

اَللَّهُمَّ إِنِّي أَسْأَلُكَ بِأَنَّ لَكَ الْحَمْدُ لَا إِلَهَ إِلَّا أَنْتَ الْمَنَّانُ بَدِيعُ السَّمَاوَاتِ وَالْأَرْضِ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ يَا حَيُّ يَا قَيُّوْمُ

Transliteration

Allaahumma inni as'aluka bi-anna lakal-hamdu, laa ilaaha illaa antal-mannanu badi'us-samawaati wal-ardi, yaa dhal-jalaali wal-ikraam! Yaa hayyu yaa qayyum

Meaning

O Allah, I ask Thee by virtue of the fact that praise is due to Thee, there is no deity but Thou, Who showest favour and beneficence, the Originator of the Heavens and the earth, O Lord of Majesty and Splendour, O Living One, O Eternal One.
