Salaah

Q: I'm little confused regarding salah which we performed during our stay in Makkah and hajj. We followed one book which had mentioned that your stay in Makkah, if less than 15 days then you should perform qasar salah. Also during hajj days if your stay till 7th Zil haj is less than 15 days you need to do qasar in hajj.

1. We started from India on 4th Aug 4pm and reached our hotel on 5th 00:30. As per booking, we calculated our stay as 14 days (5 to 18) and we had intention that on 18th night or 19th morning we will leave for Mina. We left Mina 19th morning 03:00am. We offered qasar all in Makkah and during haj. Is it correct?

2. How are 15 days calculated. Is it 24 hours *15 days?

3. If some musafir prays alone and recites all 4 rakats and after 2 days remembers he is musafir and then corrects his salah to 2 rakats. What is ruling on it?

Q: If a husband and wife want to read salaah side by side and seperately (not in congregation), can they do so? I read salaah beside my husband several times and seperately (he wasn't leading me in jamaat). Are the salaah valid or should I repeat them? If I am reading salaah with my husband and he is leading me in congregation, then where should I stand? 

Q: I burst a pimple on my thigh to remove its pus, and just rubbed the pus with my fingers, then I wore my undergarment and pants without cleaning the pus and/or blood that got stuck on my thigh after rubbing the pimple, nor did I clean my hands. Now, some amount of pus will stick to my clothes.

Is it allowed or okay to pray in those clothes and without cleaning it (pus) with water on my thigh and fingers or without taking a shower? I read on some websites that a small amount of pus or blood is okay and it will not break the wudoo, but my question is, will the clothes become najis after such activity or shall I take a shower to make myself clean before I pray, or at-least clean only where pus or blood got stuck? 

Q: If I joined the maghrib salaah in the last rakaat or while the imaam was reciting tashahhud of the second rakaat, then how should I perform the two rakaats that I missed, and when should I recite the thana?

Q: If a person is offering salah at home, and he has not placed a sutra infront of him. Then is it permissible for me to walk directly infront of him? Is there any permission to walk infront of him leaving some distance, say a distance of two saffs?

Q: What masnoon duas can be read after a fardh salaah?

Q: A Salaah Time Table has one time named as 'Sehri' and another time named as 'Fajr.' Of these two, when does the time for Esha Salaah end?

Q: Is it acceptable to raise ones hands in dua immediately after salah?

Q: I have about five qadha salaat to read but I don't know what salaat they are. Can you please explain to me how I should make qadha of these salaats?

Q:

1. I heard that it is more virtuous for a female to pray at the hotel than praying in the Masjid Nabawi or at the Kabah. Is this true?

2. If so, will she be sinful for praying in these Masjids without need?

3. Also, would it be better for her to stay in the hotel than to perform nafl tawafs?
