2a] Ruling on swearing by the life of the Qur’aan

2a
Fourthly:
If your oath to your brother that he should not sleep in the house was
the result of an argument, then it is not Islamically appropriate.
When you swore that oath, what is Islamically prescribed in your case
is to break the oath and offer expiation for it, because of the report
narrated by al-Bukhaari (6718) and Muslim (1649) from Abu Moosa
al-Ash'ari(may Allah be pleased with him), according to which the
Prophet (blessings and peace of Allah be upon him) said: "By Allaah,
if Allaah wills, Ido not swear an oath then see something better than
that, but I expiate my oath and do that which is better."
And Muslim (1650) narrated that Abu Hurayrah (may Allah be pleased
with him) said: The Messenger of Allah (blessings and peace of Allah
be upon him) said: "Whoever swears an oath then sees that something
else is better than it, let him do that and offer expiation for his
oath."
An-Nawawi (may Allah have mercy on him) said:
These hadeeths indicate that if a person swears to do something or not
to do something, and breaking the oath is better than adhering to
it,it is mustahabb for him tobreak the oath and he hasto offer
expiation. This is something agreed upon. End quote.
And Allah knows best.
