Salaah

Q: If I wake up 15 minutes before fajr, can I pray tahajud or not? 

Q: Sometimes I go straight to prayer after I make wudu and some left over water from my face falls into my mouth. I heard that drinking during prayer invalidates prayer. Apparently I did not deliberately drink the water that falls from my face into my mouth and it is almost impossible for me to stop myself from swallowing it along with my saliva once it gets into my mouth. What should I do?

Q: I am taking a class that goes from 5:30 pm to 8:30 pm. Hence it covers asr and maghrib prayers. The class is located far away from where I live. In order to maintain purity (wudhu) for both prayers (there is no cleaning facility at the class location) I used to hold myself not to urine during the entire 3 hour session. Hence for both prayers, especially for the maghrib prayer, I am exerting a huge effort not to let anything come out during the prayer (3 hours are very long). Is my prayer valid?

In addition, even though I tried my best, I cannot guarantee that my pants is 100% clean when I start praying as it is possible that some urine come out while I was in the classroom (that is outside the prayer, before it starts). Does this possible impurity affect my prayer? I almost did my best but I really don't know if my prayers are valid.

Q: Recently I learned to read the Quran and learned that a lot of the surahs I recite during salah (including Fatiha), I had been misprouncing. It was small mistakes like pronouncing س in places where there should be ص or ث. Was my salah valid even with these mistakes?

Q: If a person has already performed fard salaah, and some people came to him and told him to say azaan for them so that they may perform their congregational prayer, is the azaan valid ?

Q: Is it waajib to offer salaatul kusoof?

Q: Is it permissible for someone to respond to his parents if they call him while he is in state of prayer (salaah)?

Q: Can women read ishraaq namaaz before the eid salaah?

Q: I went to Makkah Muazzama for hajj on 12 August, and stayed there till 30 August. Before traveling from my home country, I already intended that I will stay in Makkah Muazzama for more than 15 days. On 19 August, I was in Mina. Was I supposed to perform qasar salah or should I have performed full salah?

Q:

1. When I make wudhu, water splashes on my thighs and my pants becomes wet. So when I pray, while in the sitting position, the skin from my thighs become somewhat visible because I wear white pants. Is my prayer valid?

2. When I pray, the wind from the fan hits my clothes and the shape of my private part is visible. Also, when some people go into sajdah while wearing pants, the shape of their testes are seen, is the prayer valid?
