Salaah

Q: How long should the pause be between Surah Faatiha and a surah in salaah?

Q: I wanted to ask the mas'alah regarding children standing in saffs with the men. I always knew that small boys should stand behind the saffs of the men. However, I have noticed a trend of small boys standing next to their fathers.

It just worries me and I am inconvenienced at these small boys standing beside me in the saff. Please advise and guide as to what is correct according to Shariah.

Q: Most of the time, I feel during Salah, I didn't do sujood or didn't recite Surah Fatiha, or didn't say tashahhud or didn't pray complete rakaats so I most of the time do Sajda Sahw. Am I doing it correct?

Q: After praying Fajr, can we offer nafl or do we have to wait after sunrise?

Q: There are 2 virtues to ishraaq. One is the reward for hajj and umrah, the second is that one's day will be made easy. To get both these rewards, should 4 raka'aats be read in one go, or each set of 2 raka'aats separately?

Q: How will a person put qadha salaahs in a will because the number is constantly changing as they perform them?

Q: If I join an Eshaa Salaah behind an imaam with the intention of nafl, after missing the first 2 rakaats. Will I have to make the missed rakaats after the imaam terminates the salaah? Or will the 2 rakaats of nafl be valid and I may end the salaah with the imaam?

Q: Is it permissible to make qadhaa after asr or is it preferable to make the qadha before asr?

Also, is it permissible to make qadha salah before or after maghrib ?

Q: What is the maximum amount of rakaats one can perform in tahajjud with making salaam in the end? I heard that the most is eight rakaats, but can a person perform more than eight rakaats with making salaam at the end?

Q: As you are aware, in Gulf countries, in the Masjid after the main congregation is over, there are many second and third small congregation/jamaat prayers going on in the masjid with 5 people or 6 people or 10 people ,and so forth. As far as I know, in Hanafi Fiqh, it is not considered okay to make second jamaat in the masjid. As a Hanafi, what should a tourist visiting a Gulf country or a resident of a Gulf country do if he misses the main congregation and he sees the second smaller congregations of a handful people going on? Should he join it or should he pray the fardh separately?
