What is the ruling on one who sees moisture on his clothes and doubts whether it is semen or pre-seminal fluid (madhy)?
Whoever finds moisture upon waking from sleep and doubts whether it is semen or madhy, and cannot distinguish between them, he may choose between them and act according to his choice. If he wishes, he can consider it semen and perform the ritual bath, or consider it madhy, perform ablution, and wash what it has soiled. This is because if he fulfills the requirement of one of them, he is definitively free from it, and the default is his innocence from the other. And Allah the Almighty knows best.
What is the ruling on water that contains ornamental fish — does it become impure on account of their waste?
All praise is due to Allah, and peace and blessings be upon our master the Messenger of Allah ﷺ.
The water in a pond containing ornamental fish is pure so long as it has not been altered, for a small amount of fish waste (rawth) is pardoned and overlooked — provided it does not change the water.
It is stated in Ḥāshiyat al-Jamal ʿalā Sharḥ al-Manhaj (Vol.1/P.178): "A small amount of hair from a non-edible animal is pardoned, as is a small amount of hair from a riding animal — on account of the hardship involved in avoiding it — and likewise a small amount of fish waste is pardoned, unless it alters the water." And Allah the Almighty knows best.
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.
