end of time

Q: I find it difficult to keep wudu sometimes due to a problem. I know that I can do salah as an excused person. I read online that the excuse has to continue for an entire salah time, not giving enough time to do salah (without the excuse) and then atleast once for every salah time after to stay excused.

1. My question is that it is difficult to be paying attention to my excuse for an entire salah time to see if I qualify to be excused. It would be difficult to see if my excuse occurs every five minutes. Am I missing something? Sometimes my excuse is better than other times, but sometimes it causes me to miss salah.

2. Also, I know the one that has an excuse for wudu has to make a new wudu for each salah time. However, if the salah times run into eachother, is this still necessary. For example, if one makes wudu for asr prayer and then finishes just as maghrib is starting, does one have to leave to go make a new wudu?

3. Also, I read the an imam who suffers from an excuse (such as incontinence or the like) is not allowed to lead a normal healthy person in salah. This seems quite unfair because the excuse is not the fault of the person suffering from the excuse. If it is not a distraction to the healthy persons prayer, then it should be permitted. What is your opinions on this matter?

4. A final question I have is that if one has impurity on ones clothes and one is out and unable to clean it and the time for the salah is running out, is it better to miss the salah or pray the salah with the impurity on ones clothes (or even skin). If the person does the salah, does it have to be made up later on?

Q: Once I was in bus and the asr time was running out and due to discharge coming out I did not have wudu plus I had to wash the area, so I thought I should go home then pray but time ran out, it became qada. In this case what should have I done? Is doing tayammum by the touching the bus seat where I don't see any sand but it should be there, is valid? While praying in the bus if the bus turns it direction, is my prayer valid? Should I open my face (for salah) in front of people?

Q: Once, a few pimples on my scalp burst while I was showering and would not stop bleeding. The time for fajr salaah was almost up and my entire body was impure as the water from my head (that was still bleeding) had run all over my body. I tried to wash as much of it as I could but the majority of my body was still impure. I made wudu and performed salaah anyway, just before the time ended. Was this salaah valid? If not, what should I have done in a situation like this?

Q:

1. If a woman, to check the end of her period, cleans her private part, places a tissue there, waits 30 minutes, checks and sees no discharge - does this mean her period is over? Should she wait longer than 30 min before deciding?

2. Also at the beginning/middle of her period, does she have to make ghusl and pray during the times when blood is not flowing? For example, she sees blood at the beginning of her habit and realizes her period has started. Then she sees no blood for about half a day, then she sees blood again and the blood continues for days. During this half a day, is she considered to be on her period?

Q: How do you calculate two years of breast feeding? Say someone started breast feeding on the 5th Muharram, would the time limit be exactly on the 5th Muharram two years later or do you calculate it like iddat which would result in 24x30=720?

Q: I am currently excused (chronic excuse) with regards to wudu due to bleeding. I know that my wudu breaks when the next prayer time comes in. However once or twice I took too long to pray and when I checked the time, I was a few minutes into the next prayer time. Are those prayers invalid? Would they be invalid if I wasn't excused with regards to wudu?

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)?
