Salaah

Performing Salaah behind an Imaam with a beard

Q: I am a follower of Hanafi madhab, I have 2 masjids to pray salaah during Zohar, Asar & Magrib Salaah in my office, kindly advise in which masjid I need to pray according to Hanafi.

Masjid1: Shafi Imam with Sunnah beard but Quraan recitation is not fully tajweed

Masjid 2: Hanafi Imam(Aalim) without Sunnah Beard (i.e. Trimming the beard) but quran recitation is fully Tajweed. 

Till now I am praying behid with Shafi Imam because his beard is according to sunnah.

Changing a letter during recitation in salaah

Q: I read in a book that if you change a letter during recitation in salaah, the salaah is broken. Such as reading the letter ت instead of  د such as at the end of Surah al Falaq reading HASET instead of HASED. But somehow when I recite HASED no matter how much I pay attention to recite it with D I hear a T sound at the end coming out. Does this still break salaah? To break salaah does it need to change meaning, if HASED is read as HASET does it change meaning?
