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.
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.
Does passing wind, from the anus without a smell, invalidate prayer?
If a person is certain of having passed wind even if it was with no smell, then both his/her ablution and prayer are invalidated, thus he/she should remake ablution and re-perform prayer.
What is the ruling on someone who eats or drinks while uncertain about the arrival of dawn, then later finds out that dawn had not yet broken?
If a person does this, their fast remains valid, as it is confirmed that they ate during the night. Similarly, if someone eats while uncertain and remains unsure whether they ate before or after dawn, their fast is still valid. This is based on the maxim of Sharia Law, which states: "Certainty is not removed by doubt." Certainty, here, is the presence of night, and the doubt concerns the arrival of dawn. Therefore, one relies on certainty and disregards doubt.
