Q: When in prayer what kind of movements are allowed? For example if a person sneezes or if he feels like he might, should he cover his nose beforehand? Also, if a person leaves his saff and therefore creates an empty spot in a row, should another musalli move and cover his spot while he is praying to 'fill the gap' as mentioned in the hadith of Rasulullah (Sallallahu Alayhi Wasallam)?

Q: Why are the words of Iqaamah recited Twice(in India) when the Sahih Hadith confirms only once except Qad qaamatis Salaah as given below:

Sahih Bukhari Volume 1, Book 11, Number 579: Narrated Anas: Bilal was ordered to repeat the wording of the Adhaan for prayers twice, and to pronounce the wording of the Iqamaah once except "Qad-qamat-is-Salat".

Sahih Bukhari Volume 1, Book 11, Number 581: Narrated Abu Qilaba: Anas said, "Bilal was ordered to pronounce the wording of Adhaan twice and of Iqaamah once only." The sub narrator Isma'li said, "I mentioned that to Aiyub and he added (to that), "Except Iqaamah (i.e.Qad-Qamatis-Salat which should be said twice)."

Q: I performed isha whilst being a traveller but I returned home before fajr time. Will it be ok for me to perform 2 rakaats isha followed by 3 witr (and skip the sunnats since they are not emphasized then), or must I since I know that I will return home before fajr also pray the sunnats (either whilst on the journey or when coming home)?

Q: I started praying magrib alone before another brother joined me, so during the second rakaat I recited only one verse from the Quran (sura ghafir verse 44) after fatiha and went to ruku position. Since then I have been having doubts if my salaah is valid or not. If not what should I do because that brother is gone now.
