Doing plastic surgery to straighten the nose

Q: My daughter has a strange nose. It is very asymmetrical where one side is bigger, wider and a different shape. It does not bother her or cause her physical harm and she is unaware due to young age but I fear when she does realise this defect. I contemplate would she be able to do plastic surgery in order to correct this and if not, what actions should I take so that she does not feel insecure?

Giving zakaat to shias, qadiyaanis, etc

Q:

1) I know that it is not permissible to give zakaat to any non-Muslim. However, generally we are allowed to help needy and poor non-Muslims. The question is, there are some groups such as Shia, Qadiyani, Munkireen e Hadith which claim to be Muslim but in reality they are out of the fold of Islam. These three groups mentioned above(and probably some other groups also) are known as Zindeeq. Is my understanding correct?

2) Is it permissible to help poor and needy people belonging to such Zindeeq groups?

3) Is it permissible to give any other sort of help and aid (not financial) to these Zindeeq groups?

Making dua for the Hidaayat of non-Muslim children

Q: I have adopted Islam and married a Muslim man. I have two daughters from my earlier marriage who was a Hindu man. My daughters have not adopted islam yet. We keep on trying to make them understand and adopt Islam. My elder daughter is fifteen years old and younger one is 13 years old. Elder daughter gets angry whenever we talk about changing religion and wants that we should not talk to her regarding religion in future. Younger one says she will very soon adopt Islam. I want to know how should my husband interact with my elder daughter after knowing that she will never convert to Islam? I also want to know can my husband make dua for them as they are non-muslims but they are his daughters?
