"When it was the day of (the battle of) Uhud, the pagans were defeated. Then Satan shouted, "O
Allah's worshipers! Beware of what is behind you!" So the front files attacked the back files of the
army. Hudhaifa looked, and behold, there was his father, Al-Yaman (being attacked) ! He shouted (to
his companions), "O Allah's worshipers, my father, my father!" But by Allah, they did not stop till
they killed him (i.e., Hudhaifa's father). Hudhaifa said, "May Allah forgive you." (`Urwa said,
Hudhaifa continued asking Allah's Forgiveness for the killer of his father till he died.
Sahih al-Bukhari Book 87, Hadith 28
Yahya related to me from Malik from Suhayl ibn Abi Salih from his
father from Abu Hurayra that the Messenger of Allah, may Allah bless
him and grant him peace, said, "Whoever makes an oath and then sees
that something else would be better than it, should do kaffara for his
oath and do what is better."
Yahya said that he heard Malik
say, "Anyone who says that he has a vow but does not mention the name
of Allah, is still obliged to make the kaffara for an oath (if he
breaks it)".
Malik said, "Emphasis is when a man swears one
thing several times, repeating the oath in his speech time after time.
For instance, the statement, 'By Allah, I will not decrease it from
such-and-such,' sworn three times or more. The kaffara of that is like
the kaffara of one oath. If a man swears, 'I will not eat this food or
wear these clothes or enter this house,' that is all in one oath, and
he is only obliged to do one kaffara. It is the same for a man who
says to his wife, 'You are divorced if I clothe you in this garment or
let you go to the mosque,' and it is one entire statement in the
normal pattern of speech. If he breaks any of that oath, divorce is
necessary, and there is no breaking of oath after that in whatever he
does. There is only one oath to be broken in that."
Malik
said, "What we do about a woman who makes a vow without her husband's
permission is that she is allowed to do so and she must fulfill it, if
it only concerns her own person and will not harm her husband. If,
however, it will harm her husband, he may forbid her to fulfill it,
but it remains an obligation against her until she has the opportunity
to complete it."
Muwatta Malik Book 22, Hadith 12
Mu’awiyah came out to the Masjid and said: “What has caused you to gather for this sitting.” They said: “We gathered so that we may remember Allah.” He said, “By Allah, nothing caused you to gather for this sitting except for that?” They said, “By Allah, nothing caused us to gather for this sitting except for that.” He said: “Indeed, I did not ask you out of suspicion, and there was no one in the position I was from the Messenger of Allah who narrates less Ahadith from him than me. Indeed the Messenger of Allah came out upon a circle of his Companions and said: ‘what has caused you to gather for this sitting?’ They said: ‘We have gathered for this sitting to remember Allah, and praise Him for His having guided us to Islam, and having bestowed blessings upon us.’ So he said: ‘By Allah, nothing caused you to gather for this sitting except for that?’ He said: ‘Indeed, I did not ask you out of suspicion, verily Jibra’il came to me and informed me that Allah boasts of you to the angels.’”
