وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " إِذَا دَعَا أَحَدُكُمْ فَلَا يقُلْ: اللهُمَّ اغفِرْ لي إِنْ شِئتَ ارْحمْني إِنْ شِئْتَ ارْزُقْنِي إِنْ شِئْتَ وَلِيَعْزِمْ مَسْأَلَتَهُ إِنَّه يفعلُ مَا يَشَاء وَلَا مكره لَهُ ". رَوَاهُ البُخَارِيّ

He reported God's messenger as saying, “When one of you makes supplication he must not say, ‘O God, forgive me if Thou wilt, show mercy to me if Thou wilt, provide for me if Thou wilt’, but must make his request definite, for He does what He wills and there is no one to impose compulsion on Him.” Bukhari transmitted it.
