What is the ruling on the frequent making of vows and oaths to the extent that it has become an ordinary matter for him?

A Muslim must guard his tongue from excessive oaths and vows. The Qur’an indeed condemns excessive swearing. As for frequent and repeated oaths, if a person swears an oath and then breaks it, then swears another oath and breaks it again, a separate expiation is required for each new oath. If a person swears several oaths concerning different matters, then according to the majority of scholars, an expiation is required for each oath, while according to the Hanbalis, only one expiation is required. However, if a person swears several oaths concerning a single matter and then breaks them, the preponderant opinion is that only one expiation is to be offered.

Regarding vows, if they are conditional upon the occurrence of specific events and these events occur, then one must fulfill all of them. As for unconditional vows, they become binding as soon as they are made, and if expiation becomes necessary, a single expiation is not sufficient for all of them. Whoever neglects to fulfill a vow despite being able to do so has disobeyed Allah.
