Narrated Abdullah ibn AbuAwfa:

A man came to the Prophet ﷺ and said: I cannot memorise anything from the Qur'an: so teach me something which is sufficient for me. He said: Say Glory be to Allah, and praise be to Allah, and there is no god but Allah, and Allah is most great, and there is no might and no strength but in Allah.

:He said: Messenger of Allah, this is for Allah, but what is for me? He said: Say: O Allah have mercy on me, and sustain me, and keep me well, and guide me. When he stood up, he made a sign with his hand (indicating that he had earned a lot).

The Messenger of Allah ﷺ said: He filed up his hand with virtues.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعُ بْنُ الْجَرَّاحِ، حَدَّثَنَا سُفْيَانُ الثَّوْرِيُّ، عَنْ أَبِي خَالِدٍ الدَّالاَنِيِّ، عَنْ إِبْرَاهِيمَ السَّكْسَكِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى، قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنِّي لاَ أَسْتَطِيعُ أَنْ آخُذَ مِنَ الْقُرْآنِ شَيْئًا فَعَلِّمْنِي مَا يُجْزِئُنِي مِنْهُ . قَالَ " قُلْ سُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ وَلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ " . قَالَ يَا رَسُولَ اللَّهِ هَذَا لِلَّهِ عَزَّ وَجَلَّ فَمَا لِي قَالَ " قُلِ اللَّهُمَّ ارْحَمْنِي وَارْزُقْنِي وَعَافِنِي وَاهْدِنِي " . فَلَمَّا قَامَ قَالَ هَكَذَا بِيَدِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ " أَمَّا هَذَا فَقَدْ مَلأَ يَدَهُ مِنَ الْخَيْرِ " .
