Quranic Dua 60:04 (Surah al-Mumtahanah)
Our Lord! In You we put our trust, and to You we turn repentant, and to You is the return.
In this verse, Allah has presented the example of Prophet Abraham (AS) and his strong faith, when Prophet Abraham (AS) disassociated himself from the disbelievers including his father who refused to believe in the Pneness of Allah. Prophet Abraham (AS) asked his father to worship Allah and asked Forgiveness from Allah for his father. This Dua is the part of the verse in which Prophet Abraham (AS) expresses his faith in Allah.
