Does using a respiratory device (oxygen) affect the validity of fasting?
Using an oxygen device does not affect the validity of fasting because oxygen is a gas with no physical substance.
However, if medicinal substances with physical particles are added to the oxygen, its use would break the fast, as it enters the body cavity through a natural passage.
What is the ruling of Islamic Law on opening an account in a commercial bank in order to deposit a sum and use it for personal purposes, such as transfers and electronic payments?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is forbidden for a Muslim, if he has a choice, to open an account in an interest-based (ribawī) bank, even if the account earns no interest, because doing so assists in ribā, based on the saying of Allah the Exalted (which means): “And cooperate in righteousness and piety, but do not cooperate in sin and aggression.” [al-Māʾidah/2]
This is because such banks invest deposited funds in forbidden ribā-based transactions, and depositing with them is therefore a form of assisting them in what is unlawful. Assisting in what is unlawful is prohibited by the Sharīʿah. However, if there is a pressing need to open an account in an interest-based bank and it is not possible to open one in an Islamic bank, there is no objection to doing so.
The ruling on bank interest and the prizes distributed by interest-based banks was previously explained in Fatwa no. (
471). And Allah Almighty knows best.
Can someone who begins a voluntary fast break it?
It is preferable for someone who begins an act of worship not to break it.
Allah the Exalted has said {what means}: "and let not your [good] deeds come to nought!" [Muhammad/33].
However, if a person starts a voluntary fast (nafl) and needs to break it, they are going against what is preferable, but there is no sin upon them.
