Q: Is lying in a joke permissible?

Q: Humble request for advice regarding the following:

An elderly family member recently forwarded me and other members the following email. I would like to know if I should advise him to renew his Kalimah. He has propagated something which casts a doubt on the fundamental beliefs of Islam. Hereunder is the message:

Q: If "Rabbanaa lakal hamd" the word hamd at the end is sounded as a ت and not د will the salaah brake? The letters ت and د are they from same makhraaj, and so there is no zallatul qari is these are replaced by eachother not on purpose?

Q: Can the trustees of the masjid ban the reading of Fazzail e a'maal? (The trustee doesn't allow jamaats to read this profound kitaab).

Q: Are hanafis allowed to follow a shafi Imaam in witr during Ramadan? (The scholar claims it is allowed and its to bring the community together.)

Q: In our masjid there is a scholar but he is not an Aalim. He gives the Jummah Khutba in English. Is this allowed? Is the Jummah salaah accepted?

Q: I read in a book that to read Sami Allahu liman hamidah, to read hamidah with a soft h i.e. a ه will break salaah. Why is that? The meaning is changed? What if it happened unintentionally?

Q: I need a dua to read. My husband is in another country and he was on a journey and he was on the phone text with me and half way his phone just
went off. It's been 8 days his phones are off and never reach his house in Afghanistan. Please give me something to read so I can find him or any news of his to come to me. I'm so worried Ya Allah help me and my kids and my husband.

Q: For repentance you need to feel guilty about the sin you committed. I don't feel guilty in my heart, can I verbally say that I feel guilty about the sin, would that be enough? I can say verbally "I regret doing the sin, I shouldn't have done the sin" would that be enough?

Q: I am 7 months pregnant and suffer from backaches and leg pains. Will it be permissible for me to sit and read salaah when the pain is very severe?
