Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, ''When you are making dua do not say; 'O Allah, forgive me if You wish. O Allah, forgive me if you wish.' You should be firm in your asking, for there is no compelling Him."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَقُلْ أَحَدُكُمْ إِذَا دَعَا اللَّهُمَّ اغْفِرْ لِي إِنْ شِئْتَ اللَّهُمَّ ارْحَمْنِي إِنْ شِئْتَ لِيَعْزِمِ الْمَسْأَلَةَ فَإِنَّهُ لاَ مُكْرِهَ لَهُ
