Abu Musa reported God’s messenger as saying, “Feed the hungry, visit the sick and free the captive.” Bukhari transmitted it.

The Messenger of Allah (saws) as saying: Feed the hungry, visit the sick and free the captive. Sufyan said: al-'ani means captive.

"I heard Abu Juhaifah say: 'We asked 'Ali: "Do you have anything from the Messenger of Allah apart from the Qur'an?" He said: "No, by the One who splits the seeds and creates the soul, unless Allah gives a slave understanding of His Book, or except this sheet." I said: "What is in the sheet?" He said: "In it are (the regulations concerning) blood money and the freeing of captives and (the rule) that no Muslim should be killed for killing a disbeliever."

"Al-Abbas and Ali came to 'Umar with a dispute. Al-Abbas said: 'Pass judgment between him and I.' the people said: 'Pass judgment between them.' 'Umar said: 'I will not pass judgment between them. They know that the Messenger of Allah said: We are not inherited from, what we leave behind is charity. He said: And (in this narration of it) Az-Zuhri said: 'It (the Khumus) was under the control of the Messenger of Allah , and he took provision for himself and for his family from it, and disposed to the rest of it as he disposed of other wealth (belonging to the Muslims). Then Abu Bakr took control of it, then I took control of it after Abu Bakr, and I did with it what he sued to do. Then these two came to me and asked me to give it to them so that they could dispose of it as the Messenger of Allah disposed of it, and as Abu Bakr disposed of it, and as I disposed of it. So I gave it to them and I took promises from them that they would take proper care of it. Then they came to me and this one said. Give me my share from my brothers son: and this one said: Give me my share from my wife. If they want me to give it to them on the condition that they would dispose of it in the same manner as the Messenger of Allah did, and as Abu Bakr did, and as I did, I would give it to them, but if they refuse, then they do not have to worry about it.' Then he said: 'And know that whatever of spoils of war that you may gain, verily, one-fifth of it is assigned to Allah, and to the Messenger, and to the near relatives (of the Messenger (Muhammad), (and also) the orphans, Al-Masakin (the poor) and the wayfarer' (Al-Anfal 8:41) this if for them. 'As-Sadaqat (here it means Zakah) are only for the Fuqara (poor), and Al-Masakin (the poor) and those employed to collect (the funds); and to attract the hearts of those who have been inclined (toward Islam); and to free the captives; and for those in debt; and for Allah's cause (I.e. for Mujahidun - those fighting in a holy battle)' - this is for them. 'And what Allah gave as booty (Fay') to His Messenger (Muhammad) from them - for this you made no expeditin with either cavalry or camels.' Az-Zuhri said: This applies exclusively to the Messenger of Allah and refers to an 'Arab village called Fadak, and so on. What Allah gave as booty (Fay') to His Messenger (Muhammad) from the people of the townships - it is for Allah, His Messenger (Muhammad), the kindred (of Messenger Muhammad), the orphans, Al-Masakin (the poor), and the wayfarer (And there is also a share in this booty) for the poor emigrants, who were expelled from their homes and their property And (it is also for) those who, before them, had homes (in Al-Madinah) and had adopted the Faith And those who came after them. These is no one left among the Muslims but he has some rights to this wealth, except for some of the slaved whom you own. If I live, if Allah wills, I will give every Muslim his right." Or he said: "His share."

On the day of Badr, the Messenger of Allah (ﷺ) looked at his companions and they were three hundred and some, then he looked at the mushrikeen and saw that they were one thousand or more. The Prophet of Allah(ﷺ) turned to face the qiblah, then he stretched forth his hands, wearing his upper and lower garment, and he said: “O Allah, where is Your promise to me? O Allah, accomplish for me what You have promised me! O Allah, if this small band of Muslims is destroyed, You will never be worshipped on earth.” He kept beseeching his Lord, calling out to Him, until his upper garment fell from his shoulders. Abu Bakr came to him, picked up his upper garment and put it on him. Then he embraced him from behind and said: O Prophet of Allah, this prayer of yours to your Lord will suffice, for He will accomplish for you what He has promised to you. Then Allah revealed the words: `(Remember) when you sought help of your Lord and He answered you (saying): ‘I will help you with a thousand of the angels each behind the other (following one another) in succession` [al Anfal 8:9). On that day when the armies met (in battle), Allah, may He be glorified and exalted, defeated the mushrikeen; seventy of their men were killed and seventy were taken captive. The Messenger of Allah (ﷺ) consulted Abu Bakr, 'Ali and 'Umar رضي الله عنهم (concerning the prisoners). Abu Bakr said: O Prophet of Allah, they are our cousins, kinsmen and brothers, I think that you should accept a ransom for them, which will strengthen us against the kuffar, and perhaps Allah will guide them to Islam and they will become a support to us. The Messenger of Allah (ﷺ) said: “What do you think, O son of al-Khattab?` I said: No, by Allah. I do not think as Abu Bakr thinks. I think that you should hand. So and so ­ a relative of ʼUmar's- ­ over to me so that I may strike his neck. You should hand ‘Aqeel over to ‘Ali so that he may strike his neck, and you should hand over So and so to Hamzah (his brother) so that he may strike his neck, so that Allah will know that we have no mercy in our hearts towards the mushrikeen; these are their prominent figures and leaders. But the Messenger of Allah (ﷺ) inclined towards the view of Abu Bakr, and he did not incline towards what I said, and accepted ransoms from them. The next day, I came to the Prophet (ﷺ) and found him with Abu Bakr, and they were both weeping I said: O Messenger of Allah , tell me why you and your companion are weeping. If I find it is a cause for weeping, I will weep too, and is it is not, then I will make myself weep with you. The Messenger of Allah (ﷺ) said: `I am weeping because of what your companions suggested about accepting a ransom for the prisoners. I have been shown your punishment as close as this tree` ­ a tree that was close to the Prophet of Allah (ﷺ) Then Allah revealed the words:`It is not for a Prophet that he should have prisoners of war (and free them with ransom) until he had made a great slaughter (among his enemies) in the land. You desire the good of this world (i.e. the money of ransom for freeing the captives), but Allah desires (for you) the Hereafter. And Allah is Almighty, All Wise. Were it not a previous ordainment from Allah, a severe torment would have touched you for what you took `[al Anfal 8:67­-68] ­ i.e., referring to the ransom. Then booty was permitted to them, and when the day of Uhud came the following year, they were punished for what they had done of taking the ransom on the day of Badr. Seventy of them were killed and the Companions of the Prophet deserted him, his front tooth was broken and the helmet on his head was broken, and blood flowed down his face, and Allah revealed the words: “When a single disaster smites you, although you smote (your enemies) with one twice as great, you say: 'From where does this come to us?`Say (to them), ‘It is from yourselves (because of your evil deeds).' And Allah has power over all things” [Al 'Imran 3:165]

Abu Bakr came to him, picked up his upper garment and put it back on him. Then he embraced him from behind and said, “O Prophet of Allah, this prayer of yours to your Lord will suffice, for He will accomplish for you what He has promised to you.” Then Allah revealed the words: “(Remember) when you sought help of your Lord and He answered you (saying): ‘I will help you with a thousand of the angels each behind the other (following one another) in succession’” (al-Anfal 8:9).
