Is my husband entitled to take my salary?
Your salary is yours, and you may give some of it to him as a kind of free-will contribution.
Is vomit among the nullifiers of Wudu (ablution)?
Vomit does not nullify Wudu, but it is a Najaasah (impurity) that requires rinsing the mouth and washing whatever became dirty by it since the prayer becomes valid only after the removal of Najaasah. And Allah Knows Best.
Is it permissible to single out Fridays, Saturdays, and Sundays to make up for missed fasting without fasting a day before ,or after each ?
Yes, it is permissible to make up for missed fasting during the aforesaid days, and it is also valid to offer non-obligatory and vowed fasting as well. However, fasting a day before or after each isn`t obligatory. And Allah Knows Best.
I wear braces because I had an accident. However, Iam afraid that I could die and be buried while wearing them because they are permanent installation. Is this forbidden? I also wear false teeth. Should I ask my children to pull them out after I die?
All perfect praise be to Allah the Lord of The Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
If the braces are worn to get teeth back to normal, then there is no sin in that and there is also no harm in wearing false teeth. Moreover, you don`t have to have them removed after your passing away as this undermines the dignity of the dead. And Allah The Almighty Knows Best.
