Yahya related to me from Malik from Hisham ibn Urwa that his
father said, "The Messenger of Allah, may Allah bless him and grant
him peace, was asked, 'Messenger of Allah! Some people from the desert
bring us meat, and we do not know whether the name of Allah has been
mentioned over it or not.' The Messenger of Allah, may Allah bless him
and grant him peace, said, 'Mention the name of Allah over it and
eat.' "
Malik said, "That was in the beginning of Islam."
Muwatta Malik Book 24, Hadith 1
Yahya related to me from Malik from Hisham ibn Urwa that his
father said, "Someone who does not stand at Arafa on the night of
Muzdalifa
before the dawn breaks has missed the hajj, and
some one who stands at Arafa on the night of Muzdalifa before the dawn
breaks has caught the hajj.
Malik said, about a slave freed
during the wuquf at Arafa, "His standing does not fulfil for him the
hajj of Islam, except if he was not in ihram and then he went into
ihram after he was freed and he stood at Arafa that same night before
the dawn broke in which case that is enough for him. If, however, he
did not go into ihram until after the dawn had broken, he is in the
same position as someone who misses the hajj by not catching the
standing at Arafa before the breaking of the dawn on the night of
Muzdalifa, and he will have to do the hajj of Islam later."
Muwatta Malik Book 20, Hadith 182
From his father, from his grandfather, that the Messenger of Allah (ﷺ) said: "Both the buyer and the seller retain the option as long as they did not separate, unless they agreed to making it optional. And it is not lawful for him to separate from his companion, fearing that he will change his mind."
This Hadith is Hasan and this means separating from him after the sale, fearing that he will change his mind. And if the separation referred to speech, and there was no option left for him after the sale, then this Hadith would be meaningless, since he (ﷺ) said: "And it is not lawful for him to separate from his companion, fearing that he will change his mind."
Jami` at-Tirmidhi Book 14, Hadith 47
Uwaimir Al-`Ajlani came to `Asim bin Adi Al-Ansari and asked, "O `Asim! Tell me, if a man sees his
wife with another man, should he kill him, whereupon you would kill him in Qisas, or what should he
do? O `Asim! Please ask Allah's Messenger (ﷺ) about that." `Asim asked Allah's Messenger (ﷺ) about that. Allah's
Apostle disliked that question and considered it disgraceful. What `Asim heard from Allah's Messenger (ﷺ)
was hard on him. When he returned to his family, 'Uwaimir came to him and said "O `Asim! What did
Allah's Messenger (ﷺ) say to you?" `Asim said, "You never bring me any good. Allah's Messenger (ﷺ) disliked to
hear the problem which I asked him about." 'Uwaimir said, "By Allah, I will not leave the matter till I
ask him about it." So 'Uwaimir proceeded till he came to Allah's Messenger (ﷺ) who was in the midst of the
people and said, "O Allah's Messenger (ﷺ)! If a man finds with his wife another man, should he kill him,
whereupon you would kill him (in Qisas): or otherwise, what should he do?" Allah's Messenger (ﷺ) said,
"Allah has revealed something concerning the question of you and your wife. Go and bring her here."
So they both carried out the judgment of Lian, while I was present among the people (as a witness).
When both of them had finished, 'Uwaimir said, "O Allah's Messenger (ﷺ)! If I should now keep my wife
with me, then I have told a lie". Then he pronounced his decision to divorce her thrice before Allah's
Apostle ordered him to do so. (Ibn Shihab said, "That was the tradition for all those who are involved
in a case of Lian."
