● It is preferable to fast consecutively when making up missed fasts if they were missed due to a valid excuse.

● However, if the fasts were missed without a valid excuse, then fasting consecutively is obligatory, because making up the missed fasts in this case must be done immediately.

Separating the makeup fasts goes against the obligation of immediacy, but if someone does so, their fasts will still be valid. However, they will be sinful for delaying without a valid reason.

● If a sick person starts the day fasting and then recovers during the day, they must complete their fast.

● If a traveler starts the day fasting and then settles (returns or stops traveling) during the day, they must also complete their fast.

● It is forbidden for both of them to break their fast because the concession (rukhsah) is no longer valid once its reason disappears.

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.

 

If someone swears by Allah without intending to take an actual oath, and without the firm resolve to bind themselves to it, then there is no sin or expiation (Kaffarah) required of them. Allah the Exalted says {what means}: 'God will not call you to account for thoughtlessness in your oaths, but for the intention in your hearts; and He is Oft-forgiving, Most Forbearing.' [Al-Baqarah/225]. However, a Muslim should avoid swearing oaths excessively so that their tongue does not become accustomed to it. Allah the Exalted says {what means}: 'And make not God’s (name) an excuse in your oaths against doing good, or acting rightly, or making peace between persons; for God is One Who heareth and knoweth all things.
' [Al-Baqarah/224]. And Allah the Exalted knows best."
