Should nail polish be removed before making ablution?
Yes, it should be removed because it prevents water from reaching the nails.
What should one who doubts the validity of his ablution and performs it frequently do?
Whoever doubts the validity of his ablution after finishing it, his ablution is valid. This is because the default is the validity of the ablution, and because doubt after finishing an act of worship doesn`t affect its validity. And Allah the Almighty knows best.
How is the niṣāb (minimum threshold) of gold calculated when one owns gold of multiple different karats?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah ﷺ.
Zakāh is obligatory on cash and on gold designated for saving or for trade, provided the total reaches the niṣāb (minimum threshold liable for Zakah), and a full ḥawl (lunar year) has elapsed over it. The niṣāb is (85) grams of 24-karat gold; for 21-karat gold, the niṣāb equals (97) grams; and for 18-karat gold, it equals (113) grams.
If one owns gold of multiple different karats, the person paying zakāh should calculate the monetary value of all the gold he owns, combining these values together to determine whether the total reaches the niṣāb. He then pays zakāh on this combined monetary value, once the total reaches the niṣāb. The relied-upon position is to calculate the zakāh based on the buying price [i.e., the price the gold merchant would pay the owner to purchase the gold from him] on the day the zakāh obligation is due. And Allah, the Exalted, 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.
