Government employee accepting gifts from the public

Q: I'm a government empoloyee and I get a salary per month. In our country there is a common trend of people who come to government offices for their needs to give some extra amount to employees working in various departments even if it is not compulsary to give that amount because they are afraid that work will not be done on time.

1. Can I take that amount if somebody is giving me in a similar fashion because of the trend? I never forced them to give that amount.

2. Can I take an extra amount if my officer gives to me but he received it from other people? (Officer takes amount somewhat forcefully from people)

Abusive father

Q: My parents have been divorced. My father who is a foreigner lives alone. He is verbally and emotionally abusive to myself and siblings. I want to maintain good relations with him however each time I would try to engage with him he would react abusively by saying nasty things about my family members and by cursing myself and family members. (Cursing my mother, brother, sister, husband, etc.). What should I do? Is there any Amal I could do in particular to help this situation?

Keeping qadha fasts in sequence

Q: Suppose a person has missed fasts of so many years. She also has to fast the days of her periods of the previous Ramadan. Can she first fast for the period days and then make up the fasts of previous 5 to 6 years? Or the fasts have to be kept in sequence. By keeping in sequence it might happen that she doesnot get the time for keeping her period fasts before the next Ramadan.

Mistakenly drinking water while fasting

Q: A person forgetfully drinks water in Ramadan. While drinking water he suddenly remembers that he is fasting. He stops drinking water but while he was remembering that he is fasting he might have drank a little water. That means he drinks a little water remembering that he is fasting, but he did not have any intention to break the fast. He then continues the rest of the day fasting. Is his fasting valid?
