Method of Salaah

Q: Can we start Surah Bakarah in the second rakaat when we recite Suraha Naas in the first rakaat?

Q: One recites a passage from the Quran as a Surah in salaat. However, after completion of the salaat, there is a lingering doubt in one's mind that the last ayaat was not recited correctly but cannot recall exactly what one recited. What then should one do?

Q: Can I pray my fardh namaaz without saying takbeer-e-ula when I am praying my namaaz just myself?

Q:

1. Dua I read in tashahud is: Attehhiyyatu, attayibatu, assalavatu, azzakiyyatu Lillahi. Assalamu ala nabiyi va rahmatalluahi va barakatuhu, assalamu aleina va ale ibadillahi ssalihin…. I read it was narrated by Aisha (Radiyallahu Anha) that after the death of our Nabi (Sallallahu Alayhi Wasallam) this dua was recited. Could you please tell me how authentic this hadeeth is?

2. Can I be reading this dua instead of assalamu aleyka ayyuhen nabiyu…. If I feel inside of me that I am calling to Nabi (Sallallahu Alayhi Wasallam) and it gives me waswasa that I am making shirk? Will my salah be valid in shaa Allah? And if I have no waswasa but just like this dua more because it gives me no doubts and there is no direct addressing to Nabi (Sallallahu Alayhi Wasallam), is it ok to read it?

3. I like to read Surah ikhlaas in the first two rakahs of fard namaz and in all rakahs of Sunnah namaz. I absolutely love this Surah and I know hadeeth that someone also always read it in all rakahs and nabi (Sallallahu Alayhi Wasallam) said that Allah also loves you for loving this surah. Can I continue doing so in shaa Allah? Please explain why you say it is makrooh so I can explain to my friends too?

4. In case your answer is negative in 3, can I be reading in the first rakah - surah fatiha, ihlas and first verse of falaq and in second rakah – surah fatiha and Ihlaas? I know so far - fatiha, ihlas falak, nas and ayat al kursi. But I hope in shaa Allah to read ihlas in all rakahs is not a problem, please kindly answer.

Q: I got two questions;

1. Do we need to recite anything while praying behind an Imam? Is it compulsory to read a surah?

2 When we reciting fathiha or a surah in a prayer, what if we do a mistake and we realize it at the moment, what shall we do? Example 01- When we reciting surah al naas and after recitng half we random come up with another verse of another surah like surah al quraysh. Example 02, when we reciting surah al nas half and what if we cant remember the other half ? Can we skip the surah?

Q: When the Imaam ends the qiraat before going to ruku, some people drop their hands before the Imaam says the takbir. What is the Shar'ee ruling regarding this? Is it permissible for them to drop their hands?

Q: When you perform salaah, when doing takbeer to start, should we look up or down? And after raising from rukuand saying "samirallahhulimanhamida", some says you have to say "allahumma rabbanawakalhamd" and others only "rabbana lakalhamd"? Which one is correct according to sunnah? And is it obligatory to say it? If i did not say it, are all my prayers invalid?

Q: If one just built up a lot of sweat after playing sports and it's time for Salaah, can he perform his Salaah with all that perspiration?

Q: I realized that I was reading surah Ikhlas pausing in letter Mim (everywhere where it has sukun in this surah) in last ayats making it as double letter – shadda. Does it change the meaning? If during salah I realize I did it again, do I have to start salahs from the beginning or I have to make sajda-sawh or can proceed without it as normal? Could you please also let me know, is it true that kaza of sunna of fajr cant be made in a fajr time, but has to be made any other time after fajr?

Q:

1. What is tadeel-e-arkaan?

2. Does leaving out tadeel-e-arkaan during salaah cause sajda-e-sahw to become waajib or not?
