tahaarat

Q:

1. When I start sleeping then in the beginning I don't sleep completely and some sexual things flash in my mind and some mazi comes out so this would be counted as wet dream? I am sure that I didn't have any vaginal throbbing nor did my heart beat get fast, so do I have to make ghusl?

2. When I woke up then I remember having a wet dream but there was no wetness nor mani or mazi but there was very little spot on my clothes which was looking like regular white discharge, so should I make ghusl?

Q: I did ghusl, but afterwards I found out that there were some food particles in my teeth. Do I need to do ghusl again or just rinse my mouth again?

Q: I have heard that oil prevents the water from reaching the roots of the hair. Now I am confused. If oil is applied to the hair will the ghusl be valid or do we have to use shampoo or soap to remove the oil?

Q: I have got a fat pimple or wound, which is still open. Its on my hand. It does not bleed when it is dry but when water passes on it, it gets wet, and water sits on it. When I put a tissue on it, the tissue gets stained with a dot of red or yellow colour, a little bigger than a dot. So my question is that since its on my hand, how do I do my wudhu? And the water that touches the wound is paak or napaak? 

Q: In an automatic washing machine we just have to put the clothes and the detergent and it automatically fills water and washes the clothes as well as it automatically drains the water after washing. Will the impure clothes become paak or pure? Some scholars say that washing impure clothes in an automatic washing machine does not make it paak.

Q: I understand that a Ma'zoor has to renew his wudhu for each salaah.

1. My question is that when the time for fajr ends, can I make a new wudhu as soon as fajr ends or do I have to wait for the sun to completely rise.

2. When does this wudhu end (from sunrise to what time)?

Q: If the salah time is about to end, should a person make tayammum and perform salaah or should he search for water and make qaza of his salah?

Q: I am a male and I follow the Shafi'i madhab. I need some advice for the following problems: I get clear sticky leakage in little amounts from the male organ and I cannot be sure when it will come out but I know it's bound to come out at some point. I always try to make instinja before wudu but even then the leakage is random and it occurs everyday at different times without any arousal. This problem really hinders my worship because I fear that if I make wudu and walk to the masjid it would come out and not feel it because most of the time I cant feel it come out. When reading Quran it may also come out and then I don't know it. When Jumuah comes around I fear that my wudu would break before jumuah salah then I don't even know it. I'm not sure if I'm excused or not. If I am an excused person what is the difference between the Shafi'i and Hanafi way. I once wiped my phone with methylated spirits because I needed to stick on a screen protector. Is my phone napak?
