Q: How to attain khushoo and khudhoo permanently in salaah despite having doubts all the time? 

Q: Do I have to wear a topi when performing salaah, or can I perform salaah without a topi? 

Q: What is the procedure of doing binaa in salaat? Do you have to go back to the same place in Haram or is it ok to read from anywhere in the Haram once you have redone your wudhu.

And how do you rejoin the salat, in which rakaat etc in the situation where the imam has already finished?

Q: If an Imam is leading an obligatory prayer in the Masjid and an earthquake strikes severely, under the Shariah, should he not suspend that salah and ensure for human safety and not show heroism? Taking the cue from the ruling on rains and harsh cold weather and the Prophet (sallallahu alaihi wasallam)'s command to stay at home and pray, is earthquake not a bigger calamity?
