The prophet (saw) said that Allah is shy, when his servants raise his hands in dua/ supplication to let them come down empty without being answered. Allah (swt) Allah subhanaw Taala is shy and generous so that when a servant raises His hands to the sky, there’s no way that Allah (swt) would let those hands come down from the heavens empty and rejected.
ALLAHUMMA ANTA RABBI IN ARABIC TEXT
In arabic the dua is written,
اللّٰهُمَّ أَنْتَ رَبِّي، لَا إِلٰهَ إِلَّا أَنْتَ، خَلَقْتَنِيْ وَأَنَا عَبْدُكَ، وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ، أَعُوْذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ، أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَىَّ وَأَبُوءُ لَكَ بِذَنْبِيْ، فَاغْفِرْ لِيْ، فَإِنَّهُ لَا يَغْفِرُ الذُّنُوْبَ إِلَّاأَنْتَ۔
TRANSLITERATION OF SYED UL ISTIGHFAR
Here’s transliteration to help with pronunciation of the dua,
Allahumma anta rabbi la ilaha illa anta, khalaqtani wa-ana ‘abduk, wa-ana ‘ala ‘ahdika wawa‘dika mas-tata‘t, a‘oothu bika min sharri ma sana‘t, aboo-o laka bini‘matika ‘alay, wa-aboo-o bithanbee, faghfir lee fa-innahu la yaghfiru-thunaba illa ant
O Allah, You are my Lord, none has the right to be worshipped except You, You created me and I am Your servant and I abide to Your covenant and promise as best I can, I take refuge in You from the evil of which I have committed. I acknowledge Your favour upon me and I acknowledge my sin, so forgive me, for verily none can forgive sin except You.
[Bukhaari 7/150]
