صحيح مسلم#6813Sahihحَدَّثَنَا إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ، حَدَّثَنَا أَنَسُ بْنُ عِيَاضٍ، حَدَّثَنَا الْحَارِثُ، - وَهُوَ ابْنُ عَبْدِ الرَّحْمَنِ بْنِ أَبِي ذُبَابٍ - عَنْ عَطَاءِ بْنِ مِينَاءَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ يَقُولَنَّ أَحَدُكُمُ اللَّهُمَّ اغْفِرْ لِي إِنْ شِئْتَ اللَّهُمَّ ارْحَمْنِي إِنْ شِئْتَ . لِيَعْزِمْ فِي الدُّعَاءِ فَإِنَّ اللَّهَ صَانِعٌ مَا شَاءَ لاَ مُكْرِهَ لَهُ " .
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)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih Muslim is accepted as Sahih (authentic) by the established status of the book.
