Prophet (SAW)'s Prayers Dua after salaat of need

Abdullah bin Auf (R.A.) narrates that Prophet Mohammad (SAW.) said that if a person has a need either from Allah or man, he should perform wudhu properly, perform two rakaats Nawafil Salaat, praise Allah and send Durood to Prophet Mohammad (SAW.) and recite the following dua:

لَا إِلَهَ إِلَّا اللَّهُ الْحَلِيمُ الْكَرِيمُ سُبْحَانَ اللَّهِ رَبِّ الْعَرْشِالْعَظِيمِ، وَالْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ أَسْأَلُكَ مُوجِبَاتِ رَحْمَتِكَ وَعَزَائِمَ مَغْفِرَتِكَ وَالْغَنِيمَةَ مِنْ كُلِّ بِرٍّ وَالسَّلَامَةَ مِنْ كُلِّ إِثْمٍ لَا تَدَعْ لِي ذَنْبَاً إِلَّا غَفَرْتَهُ وَلَا هَمَّاً إِلَّا فَرَّجْتَهُ وَلَا حَاجَةً هِيَ لَكَ رِضَاً إِلَّا قَضَيْتَهَا يَا أَرْحَمَ الرَّاحِمِينَ

"There is none worthy of worship besides Allah, who is the affectionate and most helpful. He is pure and is the Lord of the Arsh (throne). All praise belongs to Allah. O Allah, I desire (seek) that which makes Your mercy compulsory and the things that necessitate Your forgiveness, and portion of every good and safety from every sin. O Merciful of the Merciful, forgive (pardon) my sins and remove all my worries and fullfil all my needs as You desire. (Tirmidhi and Ibn Maja)
