Method of Salaah

Q: After fard prayer, do you have to send salutation on Muhammad (Sallallahu Alayhi Wasallam) by reading the durood shareef? Every masjid do that but when I am doing research, in no place it is mentioned that after fard prayer, you have to send blessings on Muhammad (Sallallahu Alayhi Wasallam) (i.e Allahumma swaliraswayyidinamuhammadinwwaralaalimuhammadinwwabaarikwasallim)? Or is it that they do this because they make the congregational dua after that because durood should be recited before making dua? According to my knowledge, after fard prayer, you have to read ayat ul kursi, tasbeen e fatihi and make your own dua and some but this recitation of durood is confusing.

Q: In jalsa between two sajdah, can we read dua allahummaghfirlee warhamnee in short?

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?
