Salaah

Q: I’m currently in my haidh and travelling overseas in 2 days. I’ll be moving from city to city so I would like to know after I have my ghusl, will I perform full salah throughout my trip or not?

Q: What do I do in the case where I make a mistake during salah?

Today I made a mistake after saying samiallah hulimanhamidah, I went down to do ruku again. I suddenly stopped prayer because I realised this mistake, then redid the salah. I was on the first rakah. Is this when one does sajdah sahw? If so, how do I perform it?

Q: I returned home from a 7 day holiday in Durban. The time for Asr set in while I was driving. I reached home 45 mins before Magrib and prayed Asr 4 rakaats.

Should I have read Asr as a Musafir or full Salaah? What are the rules regarding Musafir when returning from a journey for a Salaah that has set in but only read when at home?

Q: Can I perform namaz after applying medicine on my penis? The oil is a medicine which was prescribed by the doctor.

Q: Is the ruling of 'weed' the same as khamar in the sense that if smoked, prayers are not accepted for 40 days? 

Q: What is the sunnah qiraat for the different salaah, and is it sunnah to recite it in all the salaah (i.e. sunnah, witr and fardh) or only the fardh salaah?

Q: “Quarter of the head is approximately the amount of the palm with the fingers.” So to estimate this, do I place my hand vertically on my head or horizontally?

What if some of my hair is showing and some of my awrah from my arm is showing? Do I need to add them up together? 

Q: I want to know if I will read qasr salaah if I don't know how long I will be on holiday for? Most probably it will be for more than 15 days but I'm not sure of the exact date when I will be returning home.

Q: I was reciting tashahud and I had to clear my throat and I wasnt sure if I had begun reading assalamu alaika ayyuhan nabiyyu warahmatullahi wabarakatu or if I actually already did read it and I should start reading assalamu alayna. I decided to continue by reciting assalamu alayna. Does this doubt render my salah invalid?

Q: What is the law of a Musjid-e-Kabeer and Musjid-e-Sagheer?
