A person is rewarded for what they intended even when the unintended happens

My grandfather, my father and I gave the pledge of allegiance to Messenger of Allah ﷺ. The Prophet ﷺ got me engaged and then got me married.

One day I went to the Prophet ﷺ with a complaint. My father Yazid had taken some gold coins for charity and kept them with a man in the mosque (to give them to the poor) But I went and took them and brought them to him (my father). My father said, "By Allah! I did not intend to give them to you. " I took (the case) to Messenger of Allah ﷺ . On that Messenger of Allah ﷺ said, "O Yazid, you will be rewarded for what you intended. O Ma'n, whatever you have taken is yours."  

بَايَعْتُ رَسُولَ اللَّهِ ﷺ أَنَا وَأَبِي وَجَدِّي، وَخَطَبَ عَلَىَّ، فَأَنْكَحَنِي۔ وَخَاصَمْتُ إِلَيْهِ۔

وَكَانَ أَبِي يَزِيدُ أَخْرَجَ دَنَانِيرَ يَتَصَدَّقُ بِهَا، فَوَضَعَهَا عِنْدَ رَجُلٍ فِي الْمَسْجِدِ۔ فَجِئْتُ فَأَخَذْتُهَا فَأَتَيْتُهُ بِهَا۔ فَقَالَ: وَاللَّهِ مَا إِيَّاكَ أَرَدْتُ فَخَاصَمْتُهُ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ: «لَكَ مَا نَوَيْتَ يَا يَزِيدُ وَلَكَ مَا أَخَذْتَ يَا مَعْنُ۔»

قَالَ بَايَعْتُ رَسُولَ اللَّهِ أَنَا وَأَبِي وَجَدِّي وَخَطَبَ عَلَيَّ فَأَنْكَحَنِي وَخَاصَمْتُ إِلَيْهِ وكَانَ أَبِي يَزِيدُ أَخْرَجَ دَنَانِيرَ يَتَصَدَّقُ بِهَا فَوَضَعَهَا عِنْدَ رَجُلٍ فِي الْمَسْجِدِ فَجِئْتُ فَأَخَذْتُهَا فَأَتَيْتُهُ بِهَا فَقَالَ وَاللَّهِ مَا إِيَّاكَ أَرَدْتُ بِهَا فَخَاصَمْتُهُ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ «لَكَ مَا نَوَيْتَ يَا يَزِيدُ وَلَكَ يَا مَعْنُ مَا أَخَذْتَ»  

[Machine] I pledged allegiance to the Messenger of Allah, ﷺ , along with my father and grandfather. Ali proposed to me and married me. I argued with him and he left a mark on me. My father brought two dinars to give as charity and he left them with a man. I took them and brought them to Ali. He said, "By Allah, I did not intend for you what you thought. O Yazid, you can keep what you took, O Ma'n."  

بَايَعْتُ رَسُولَ اللهِ ﷺ أَنَا وَأَبِي وَجَدِّي وَخَطَبَ عَلِيَّ فَأَنْكَحَنِي وَخَاصَمْتُ إِلَيْهِ فَفَلَجَنِي وَكَانَ أَبِي جَاءَ بِدِينَارَيْنِ يَتَصَدَّقُ بِهِمَا فَوَضَعَهُمَا عِنْدَ رَجُلٍ فَأَخَذْتُهُمَا فَأَتَيْتُهُ بِهِمَا فَقَالَ وَاللهِ مَا إِيَّاكَ أَرَدْتُ فَخَاصَمْتُهُ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ «لَكَ مَا نَوَيْتَ يَا يَزِيدُ وَلَكَ يَا مَعْنُ مَا أَخَذْتَ»  

[Machine] "My father, Yazid, had gone out with some dinars intending to give them in charity. He handed them to me and said, 'Give them to a man from the people of the mosque.' So I gave them to someone else. Then I went to my father and informed him. He said, 'That is not what I intended.' So I went to the Messenger of Allah ﷺ and disputed with him. The Messenger of Allah ﷺ said to me, 'O Ma'n, what did you take?' And he said to my father, 'O Yazid, what did you intend?'"  

كَانَ أَبِي يَزِيدَ خَرَج بِدَنَانِيرَ لَيَتَصَدَّقَ بِهَا فَدَفَعَهَا إِلَيَّ فَقَالَ ادْفَعْهَا إِلَى رَجُلٍ مِنْ أَهْلِ الْمَسْجِدِ فَدَفَعْتُهَا إِلَى غَيْرِهِ ثُمَّ أَتَيْتُ أَبِي فَأَخْبَرْتُه فَقَالَ لَيْسَ ذَاكَ أَرَدْتُ فَخَاصَمْتُهُ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ لَكَ يَا مَعْنُ مَا أَخَذْتَ وَقَالَ لِأَبِي لَكَ يَا يَزِيدُ مَا نَوَيْتَ  

[Machine] "The Messenger of Allah ﷺ, my father, my grandfather, and a man proposed to me and I married him. I argued with him and my father gave me dinars to give in charity. I placed them with a man in the mosque and went to retrieve them. I took them and brought them back to my father. He said, 'By Allah, I did not mean for you to do that.' So, I argued with him in front of the Messenger of Allah ﷺ, and he said to me, 'Yazid, you had no intention in this, and you, Ma'n, what did you take?'"  

رَسُولَ اللهِ ﷺ أَنَا وَأَبِي وَجَدِّي وَخَطَبَ عَلَيَّ فَأَنْكَحَنِي وَخَاصَمْتُ إِلَيْهِ كَانَ أَبِي يَزِيدُ خَرَجَ بِدَنَانِيرَ يَتَصَدَّقُ بِهَا فَوَضَعَهَا عِنْدَ رَجُلٍ فِي الْمَسْجِدِ فَجِئْتُ فَأَخَذْتُهَا فَأَتَيْتُهُ بِهَا فَقَالَ وَاللهِ مَا إِيَّاكَ أَرَدْتُ بِهَا فَخَاصَمْتُهُ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ لَكَ مَا نَوَيْتَ يَا يَزِيدُ وَلَكَ يَا مَعْنُ مَا أَخَذْتَ
