Sa'd bin 'Ubadah came to the Prophet and said: "My mother has died and she had a vow to fulfill but she did not do so." He said: "Fulfill it on her behalf." (Using translation from Nasāʾī 3663)  

جَاءَ سَعْدُ بْنُ عُبَادَةَ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا نَذْرٌ وَلَمْ تَقْضِهِ قَالَ «اقْضِهِ عَنْهَا»  

"I said: 'O Messenger of Allah, my mother has died; shall I give in charity on her behalf?' He said: 'Yes.' I said: 'What kind of charity is best?' He said: 'Providing drinking water.'" (Using translation from Nasāʾī 3664)  

قُلْتُ يَا رَسُولَ اللهِ إِنَّ أُمِّي مَاتَتْ أَفَأَتَصَدَّقُ عَنْهَا؟ قَالَ «نَعَمْ» قُلْتُ فَأَيُّ الصَّدَقَةِ أَفْضَلُ؟ قَالَ «سَقْيُ الْمَاءِ»  

"I said: 'O Messenger of Allah, what charity is best?' He said: 'Giving water to drink.'" (Using translation from Ibn Mājah 3684)  

قُلْتُ يَا رَسُولَ اللهِ أَيُّ الصَّدَقَةِ أَفْضَلُ؟ قَالَ «سَقْيُ الْمَاءِ»  

"O Messenger of Allah, my mother has died; can I give charity on her behalf?" He said: "Yes." He said: "What kind of charity is best?" He said: "Providing drinking water." And that is the drinking-fountain of Sa'd in Al-Madinah. (Using translation from Nasāʾī 3666)  

يَا رَسُولَ اللهِ إِنَّ أُمِّي مَاتَتْ أَفَأَتَصَدَّقُ عَنْهَا؟ قَالَ «نَعَمْ» قَالَ فَأَيُّ الصَّدَقَةِ أَفْضَلُ؟ قَالَ «سَقْيُ الْمَاءِ» فَتِلْكَ سِقَايَةُ سَعْدٍ بِالْمَدِينَةِ  

"The Messenger of Allah said to me: 'O Abu Dharr, I think that you are weak, and I like for you what I like for myself. Do not accept a position of Amir over two people, and do not agree to be the guardian of an orphan's property.'" (Using translation from Nasāʾī 3667)  

قَالَ لِي رَسُولُ اللهِ ﷺ يَا أَبَا ذَرٍّ إِنِّي أَرَاكَ ضَعِيفًا وَإِنِّي أُحِبُّ لَكَ مَا أُحِبُّهُ لِنَفْسِي لَا تَأَمَّرَنَّ عَلَى اثْنَيْنِ وَلَا تَوَلَّيَنَّ عَلَى مَالِ يَتِيمٍ  

On his father's authority, said that his grandfather told that a man came to the Prophet ﷺ and said: I am poor, I have nothing (with me), and I have an orphan. He said: Use the property of your orphan without spending it lavishly, hurrying and taking it as your own property. (Using translation from Abū Dāʾūd 2872)  

أَنَّ رَجُلًا أَتَى النَّبِيَّ ﷺ فَقَالَ إِنِّي فَقِيرٌ لَيْسَ لِي شَيْءٌ وَلِي يَتِيمٌ قَالَ «كُلْ مِنْ مَالِ يَتِيمِكَ غَيْرَ مُسْرِفٍ وَلَا مُبَادِرٍ وَلَا مُتَأَثِّلٍ»  

"When these Verses were revealed - 'And come not near to the orphan's property, except to improve it,' and 'Verily, those who unjustly eat up the property of orphans' - the people avoided the property and food of the orphans. That caused hardship to the Muslims and they complained about that to the Prophet. Then Allah revealed: 'And they ask you concerning orphans. Say: The best thing is to work honestly in their property, and if you mix your affairs with theirs, then they are your brothers. And Allah knows him who means mischief (e.g. to swallow their property) from him who means good (e.g. to save their property). And if Allah had wished, He could have put you into difficulties.'" (Using translation from Nasāʾī 3669)   

لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {وَلَا تَقْرَبُوا مَالَ الْيَتِيمِ إِلَّا بِالَّتِي هِيَ أَحْسَنُ} [الأنعام 152] وَ {إِنَّ الَّذِينَ يَأْكُلُونَ أَمْوَالَ الْيَتَامَى ظُلْمًا} [النساء 10] قَالَ اجْتَنَبَ النَّاسُ مَالَ الْيَتِيمِ وَطَعَامَهُ فَشَقَّ ذَلِكَ عَلَى النَّاسِ فَشَكَوْا ذَلِكَ إِلَى النَّبِيِّ ﷺ فَأَنْزَلَ اللهُ تَبَارَكَ وَتَعَالَى {يَسْأَلُونَكَ عَنِ الْيَتَامَى قُلْ إِصْلَاحٌ لَهُمْ خَيْرٌ} [البقرة 220] إِلَى قَوْلِهِ {لَأَعْنَتَكُمْ} [البقرة 220]  

"Verily, those who unjustly eat up the property of orphans" -A man would have an orphan in his care, and he would keep his food, drink and vessels separate. This caused hardship to the Muslims, so Allah, the Mighty and Sublime, revealed: "And they ask you concerning orphans. Say: The best thing is to work honestly in their property, and if you mix your affairs with theirs, then they are your brothers" (in religion), so it is permissible for you to mix with them. (Using translation from Nasāʾī 3670)   

فِي قَوْلِهِ تَعَالَى {§إِنَّ الَّذِينَ يَأْكُلُونَ أَمْوَالَ الْيَتَامَى ظُلْمًا} [النساء 10] قَالَ كَانَ يَكُونُ فِي حَجْرِ الرَّجُلِ الْيَتِيمُ فَيَعْزِلُ لَهُ طَعَامَهُ وَشَرَابَهُ فَشَقَّ ذَلِكَ عَلَى الْمُسْلِمِينَ فَأَنْزَلَ اللهُ تَبَارَكَ وَتَعَالَى {وَإِنْ تُخَالِطُوهُمْ فَإِخْوَانُكُمْ} [البقرة 220] وَأَحَلَّ لَهُمْ خُلْطَتَهُمْ  

The Messenger of Allah ﷺ as saying: Refrain from seven (characteristics) which cause destruction. He was asked: What are they, Messenger of Allah ? He replied: To assign partner to Allah, magic, to kill a soul (man) which is prohibited by Allah except for which is due, to take usury, to consume the property of an orphan, to retreat on the day of the battle, and to slander chaste women, indiscreet but believing. Abu Dawud said: The name Abu al-Ghaith is Salim client of Ibn Muti'. (Using translation from Abū Dāʾūd 2874)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «اجْتَنِبُوا السَّبْعَ الْمُوبِقَاتِ» قِيلَ يَا رَسُولَ اللهِ مَا هِيَ؟ قَالَ «الشِّرْكُ بِاللهِ وَالسِّحْرُ وَقَتْلُ النَّفْسِ الَّتِي حَرَّمَ اللهُ إِلَّا بِالْحَقِّ وَأَكْلُ الرِّبَا وَأَكْلُ مَالِ الْيَتِيمِ وَالتَّوَلِّي يَوْمَ الزَّحْفِ وَقَذْفُ الْمُحْصَنَاتِ الْغَافِلَاتِ الْمُؤْمِنَاتِ»
