Salatul Faatih

Q: Some Tijaniyya, not the entire group says:

Salat al-Fatih: "This prayer is 'equivalent to the recitation of all prayers of glorification to God (tasbih) that have ever been said in the universe, all Sufi prayers or remembrance of God (dhikr), every invocation (du’a) long or short . (Jawahir, p. 57.)

What is the fazaa'il of that, is it correct?

Missing an aayah in salaah

Q: While reciting qiraat in salaah, I missed the third aayah of Surah Naas (Ila hinnaas). The remainder of the surah was completed.

1) Should I have made a Sajdah e Sahw?

2) If Sajdah e Sahw was necessary, but was not made, should the salaah be repeated?

Losing one's wedding ring

Q: I am a married Muslim woman. I have lost my ring which I got as a gift on my nikaah from my husband just like an engagement ring for which I am very upset but people around me told us that losing your nikaah ring isn't a good sign for married life.

I am very much tensed and I wish that this is just a rumor, nothing else. Please tell me about it in the light of islam.
