Is it permissible to offer prayer at home, or should it be offered in the mosque?
All perfect praise be to Allah, The Lord of The Worlds. It isn`t preferable for the man to pray at home as praying in the mosque is twenty seven times more rewarding. Therefore, this should motivate him to offer prayers in the mosque. And Allah Knows Best.
What is the ruling of Islamic Law on working in hotels?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is permissible to work in hotels, restaurants, and shops in jobs that involve no direct handling of forbidden things and do not assist in them, such as administrative work.
As for jobs in which one directly handles forbidden things or assists in them, such as serving, transporting, or purchasing alcohol, receiving payment for it, or agreeing to buy it, working in them is forbidden, based on the saying of Allah the Mighty and Majestic: “And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty.” [al-Māʾidah/2]
The basic nature of the work of hotels and restaurants is permissible, and the sin of any forbidden element that arises incidentally in some of what takes place in a hotel or restaurant is borne by those who run it.
The scholars have also permitted dealing with one whose lawful wealth is mixed with unlawful wealth, as previously explained in Fatwa no. (
2697). And Allah Almighty knows best.
What should a person, who doubts the validity of his Wudu, or over performs it, do?
One who doubts the validity of his/her Wudu while performing it should redo it until he/she is certain of having attained purity. But, if doubt was after having performed Wudu, then he/she should not pay attention to that as doubt after the end of an act of worship does not count. This is of course in case doubt was within the reasonable limits since once it goes beyond that, it becomes a whispering of the Shaytaan (devil) which he/she should ignore as the Wudu is valid.
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.
