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 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 one who vows to fast a specific or non-specific year? Are the two Eids, the days of Tashreeq, Ramadan, and the days of menstruation and postnatal bleeding included in them? And do these days break the consecutiveness if it was intended?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
If someone makes a vow (Nadr) to fast a specific, designated year, this vow does not include the days of Eid, the days of Tashreeq (the three days following Eid al-Adha), Ramadan, or the days of menstruation (Hayd) and postnatal bleeding (Nifas). Furthermore, there is no requirement to make up (Qada) these specific days.
However, if someone vows to fast a year that is not specifically designated (i.e., any twelve-month period) and stipulates that the fasting must be consecutive, they are bound by that condition. They must not fast on the days of Eid, during Ramadan, or during menstruation, but they are required to make up these days afterward—with the exception of the days of menstruation and postnatal bleeding, which do not need to be made up.
It is stated in Hashiyat al-Bajuri ‘ala Sharh Ibn Qasim ({Vol.2/P.606): 'If one vows to fast a specific year, the Eid, Tashreeq, Ramadan, and days of menstruation or postnatal bleeding are not included. This is because Ramadan does not accept any fast other than its own, and the others do not accept fasting at all. Therefore, they do not enter into the vow, and no makeup is required for them because they are legally excluded—contrary to Al-Rafi’i regarding menstruation and postnatal bleeding.
If one vows to fast a non-designated year: if they stipulated consecutiveness (Tatuabu’) in their vow, they must fulfill it; otherwise, they are not bound to it. Consecutiveness is not broken by the days that do not enter into the specific year vow (Eid, Tashreeq, Ramadan, menstruation, and postnatal bleeding). However, one must make up the days missed—excluding the time of menstruation and postnatal bleeding—immediately following the end of the year. As for the time of menstruation and postnatal bleeding, it is not made up, contrary to Ibn al-Rif’ah, who argued that it must be made up just like Ramadan.' And Allah the Exalted knows best.
How should I deal with the whispers of the devil with regard to ablution and purity?
Whispers in ablution are from the devil, and so you should take refuge in Allah from the devil`s evil suggestions that aim to distort the religion. Thus, once an organ is completely pure, don`t question its purity since having whispers doesn`t mean that the purity is invalid as it has already been established.
