عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا يَقُولَنَّ أَحَدُكُمْ اللَّهُمَّ اغْفِرْ لِي إِنْ شِئْتَ اللَّهُمَّ ارْحَمْنِي إِنْ شِئْتَ وَلَكِنْ لِيَعْزِمِ الْمَسْأَلَةَ فَإِنَّهُ لَا مُكْرِهَ لَهُ
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: No one should ever supplicate in this manner: "O Allah! If You will, forgive me. O Allah! If You will, have mercy on me." Rather, he should present his request with insistence, for there is no one who can compel Allah Almighty.
