Method of Salaah

Q: A man joined the Salaah after the Imaam completed the Surah Faatihah. Should he recite sana? 

Q: If I enter the mosque to offer Maghrib or Esha namaz. I know that the people offering Namaz are in the 1st Rakat but the Imam has already started reciting a Surah from Holy Quran after reciting Surah Fatiha first. In such a situation do I have to say "Sanaa" or shall I keep silent and join the Namaz?

Q: I see that when some people from other countries pray salaah, they touch their toes and keep so much space between the shoulders. Please explain in detail if it is in Hadeeth.

Q: How long should one remain silent between fatihah and the next surah in jummah prayers? The Imams of the Haram usually remain silent after aamen for half a minute.

Q: Is it compulsory to recite Surah Fatihah in the third and fourth rakat of farz salaat. I have read somewhere that its not compulsory when reading salaat individually without jamaat.

Q: Is it permissible for the imaam to recite the sunnat duaas of qaumah and jalsah while performing fardh salaah?

Q: When we sit between the two prostations, is it mandatory to say rabbigh firlee or is it just recommened? Kindly tell me the Hanafi view regarding this and if possible please also tell me what the Maaliki, etc. say. I came to know that it is mandatory to say this and salaah is not valid without this.

Q: Let's suppose we are offering zuhr namaz or any other namaz as a muqtadi in the mosque behind the Imaam. In the second rakat when we get up from the first rakat do we have to say the "Tasmia"in the start of second rakat?

Q: I am offering namaz as a muqtadi in the mosque. I want to know that at the start of the prayer when we say "Allah hu Akbar" do we have to say "Sanna" only or do we have to say "Ta'awwuz" and "Tasmia" as well after the "Allah hu Akbar"?

Q: Which two small surahs can be recited for namaaz-e-tauba?
