Salaah

Q: What to do if I pray three rakaats Salaah in asr by mistake? Should I have to repeat the namaaz or sajdaa sahu will be enough to complete the namaz? Also if I forget which rakaat I am in, then what should I do?

Q: Zawal is at 12:10. A person starts praying at 12:05 and finishes the prayer at 12:15. Does his prayer become totally invalid and baatil due to part of it falling in zawal time, or will it still be valid but with karaahat?

Q: A drunk/intoxicated person read salaah. Will it be accepted? Will he get reward?

Q: I have just found out that I calculated my haidh incorrectly for many months due to regarding a normal discharge to be blood. Do I have to offer qadha salaah for all these months? And what is the status of the salaah I offered while I was impure? Please advise.

Q: I was calculating how many salaahs I have not read and it comes to 65 500.00 over 36 years. How do I correct?

Q: I want to know that can a person offer any Salaah during zawaal time in the evening? I had heard some Mufti saying that the particular day's asr can be offered. What is the time for zawaal before maghrib?

Q: What is the ruling for a masbooq who forgot to read a surah after surah fatiha but completed his namaz?

Q: When I am Salah in the first sitting, I cannot point my big toe forward sometimes as it cramps up so I have to move forward and just sit with my toes on the floor. Sometimes I do it just before it happens even though it has not cramped up I do it in preparation for it. Will this be regarded as too much movement and invalidate my Salaah? I sort get half up and then readjust my toe and sit down.

Q: In the musjid if someone is praying and someone goes past him with out knowing does it break his salah?

Q: My question is that I've heard that it can be wrong to say assalamu 'alaika ayyuhan Nabiyuu because the prophet sallallahu alaihi wassalam has passed away and instead we should say al-salaam 'ala al-nabi as said by Ibn Masood in Sahih bukhari. Now, majority scholars say that we should not change tashahud after the death of prophet sallallahu alaihi wassalam but my question is Ibn Masood knows better than all of the current scholars because he was a sahaba so shouldn't we follow him because he knows better the prophet sallallahu alahi wassalam?

Another issue I have is that I came across a hadith where prophet sallallahu alaihi wassalam said that no supplication is accepted unless we send peace and blessings on him. I don't remember the source of this hadith so maybe you know. So can u tell me if it mandatory to send blessings on the prophet sallallahu alaihi wassalam every time we make dua and if we forget, that dua will be incomplete?
