اللَّهُمَّ اغْفِرْ لِي إِنْ شِئْتَ اللَّهُمَّ ارْحَمْنِي إِنْ شِئْتَ . لِيَعْزِمْ فِي الدُّعَاءِ فَإِنَّ اللَّهَ صَانِعٌ مَا شَاءَ لاَ مُكْرِهَ لَهُ

The full narration
Abu Huraira reported Allah's Messenger (ﷺ) as saying:None of you should say to Allah (like this): O Allah, grant me mercy, if thou so likest. The supplication (of his) should (be permeated with) conviction (that it would be accepted by the Lord), for Allah is the Doer of (everything) He likes to do, and there is none to force Him (to do or not to do this or that)
