Feeling laughter in one's chest when performing salaah

Q: The problem I face throughout the prayer is that I feel laughter in my chest. I think it comes from fear of breaking prayer due to laughter. There are times when I compulsively (quite intentionally) pronounce letters, especially "haa", mixed with laughter and sometimes, by forgetfulness.

Most of the time, voice cracks continously while reciting and very little part of my voice is audible (due to uncleared throat) and feelings of laughter seem to get mixed. Can you please let me know what is the type of laughter that breaks Namaz? I keep feeling every Namaz is invalid.

Revoking a talaaq

Q: I gave my wife talaq once and the fatwa council has approved the talaq on the 5th of May 2023 as irrevocable divorce talaq. My wife is in her iddat period and I wanted to ask that we want to get back together what is the best way to do so? Because I gave her one talaq. Her iddat finishes on the 5th of August.
