Narrated Abu Huraira: The Prophet said, "If somebody manumits a Muslim slave, Allah will save from the Fire every part of his body for freeing the corresponding parts of the slave's body, even his private parts will be saved from the Fire) because of freeing the slave's private parts."

And Tawus said that the freeing of a Mudabbar and an Umm Walad will be sufficient.

Narrated `Amr: Jabir said: An Ansari man made his slave a Mudabbar and he had no other property than him. When the Prophet heard of that, he said (to his companions), "Who wants to buy him (i.e., the slave) from me?" Nu'aim bin An-Nahham bought him for eight hundred Dirhams. I heard Jabir saying, "That was a coptic slave who died in the same year."

Narrated `Aisha: that she intended to buy Barira (a slave girl) and her masters stipulated that they would have her Wala'. When `Aisha mentioned that to the Prophet ; he said, "Buy her, for the Wala' is for the one who manumits."

Narrated Abu Musa Al-Ash`ari: I went to Allah's Apostle along with a group of people from (the tribe of) Al-Ash`ari, asking for mounts. The Prophet said, "By Allah, I will not give you anything to ride, and I have nothing to mount you on." We stayed there as long as Allah wished, and after that, some camels were brought to the Prophet and he ordered that we be given three camels. When we set out, some of us said to others, "Allah will not bless us, as we all went to Allah's Apostle asking him for mounts, and although he had sworn that he would not give us mounts, he did give us." So we returned to the Prophet; and mentioned that to him. He said, "I have not provided you with mounts, but Allah has. By Allah, Allah willing, if I ever take an oath, and then see that another is better than the first, I make expiration for my (dissolved) oath, and do what is better and make expiration."

Narrated Hammad: the same narration above (i.e. 709), "I make expiation for my dissolved oath, and I do what is better, or do what is better and make expiation."

Narrated Abu Huraira: (The Prophet) Solomon said, "Tonight I will sleep with (my) ninety wives, each of whom will get a male child who will fight for Allah's Cause." On that, his companion (Sufyan said that his companion was an angel) said to him, "Say, "If Allah will (Allah willing)." But Solomon forgot (to say it). He slept with all his wives, but none of the women gave birth to a child, except one who gave birth to a halfboy. Abu Huraira added: The Prophet said, "If Solomon had said, "If Allah will" (Allah willing), he would not have been unsuccessful in his action, and would have attained what he had desired." Once Abu Huraira added: Allah apostle said, "If he had made the exception (i.e., said 'If Allah will')."

Narrated Zahdam al-Jarmi: We were sitting with Abu Musa Al-Ash'sari, and as there were ties of friendship and mutual favors between us and his tribe. His meal was presented before him and there was chicken meat in it. Among those who were present there was a man from Bani Taimillah having a red complexion as a non-Arab freed slave, and that man did not approach the meal. Abu Musa said to him, "Come along! I have seen Allah's Apostle eating of that (i.e., chicken)." The man said, "I have seen it (chickens) eating something I regarded as dirty, and so I have taken an oath that I shall not eat (its meat) chicken." Abu Musa said, "Come along! I will inform you about it (i.e., your oath). Once we went to Allah's Apostle in company with a group of Ash'airiyin, asking him for mounts while he was distributing some camels from the camels of Zakat. (Aiyub said, "I think he said that the Prophet was in an angry mood at the time.") The Prophet said, 'By Allah! I will not give you mounts, and I have nothing to mount you on.' After we had left, some camels of booty were brought to Allah's Apostle and he said, "Where are those Ash`ariyin? Where are those Ash`ariyin?" So we went (to him) and he gave us five very fat good-looking camels. We mounted them and went away, and then I said to my companions, 'We went to Allah's Apostle to give us mounts, but he took an oath that he would not give us mounts, and then later on he sent for us and gave us mounts, perhaps Allah's Apostle forgot his oath. By Allah, we will never be successful, for we have taken advantage of the fact that Allah's Apostle forgot to fulfill his oath. So let us return to Allah's Apostle to remind him of his oath.' We returned and said, 'O Allah's Apostle! We came to you and asked you for mounts, but you took an oath that you would not give us mounts) but later on you gave us mounts, and we thought or considered that you have forgotten your oath.' The Prophet said, 'Depart, for Allah has given you Mounts. By Allah, Allah willing, if I take an oath and then later find another thing better than that, I do what is better, and make expiation for the oath.' "
