عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَقُولَنَّ أَحَدُكُمُ اللَّهُمَّ اغْفِرْ لِي، اللَّهُمَّ ارْحَمْنِي، إِنْ شِئْتَ. لِيَعْزِمِ الْمَسْأَلَةَ، فَإِنَّهُ لاَ مُكْرِهَ لَهُ "(بُخاری شریف : ۶۳۳۹)
Translation
The Messenger of Allah (ﷺ) said: "When any of you supplicates, he should ask firmly, and should never say: O Allah! Give me if You wish, forgive me if You wish, have mercy on me if You wish, rather he should ask firmly, because there is no one who can compel Him." (Tuhfat-ul-Qari)
