Q: How we can decide when it's the right time to stop sehri?

Q: When my friend was 10 and 13 she tried committing zina with her autistic brother. She believes that at the time she didn't know what this action was. Her brother has been tested to have no sexual fantasies. She believes that the penis did not penetrate the vagina, which means this is not intercourse. She has repented and 100% knows she won't do it again. She still feels guilty, does she have to leave home, where would she go? She doesn't want to reveal this to her family. 

Q: What is the status of our currency i.e. rands and dollars? Is it thaman (money) or mabee’ (sale commodity)? In other words, what is the Islamic position on fiat money which is the currency of the majority of the world today? Some say that it is haraam and riba as the money of the Quraan Majeed and Sunnah is gold dinars and silver dirhams which have “intrinsic value”, while today’s money is backed by interest. What is the proof in the Quraan Majeed and Sunnah?

Q: Kindly explain the ruling of drinking coke as well as selling it.

Q: My mother in law has been asked by her brothers to go for Umrah with them (they will pay all the expenses) but she refuses saying that she will go for Umrah only with her sons (they dont have enough money at this point in their lives). She says that she doesn't want any favours.

The question is, is she allowed to refuse Umrah? Would it be a sin? Or can she wait for her sons to take her to Makkah.

Q: My mother got pregnant and got the baby aborted. I think it was in the first month of pregnancy. Is this considered a murder?

Q: If a person is living in his parents house and he has no resources to live somewhere else, so is it necessary in Islam to sell his parents house after their death? If he doesnt do that before getting financially stable, is there anything that his mother or father are getting gunah in the other world? I want to sell the house after some time just to ensure my mother or father is not getting any gunah for this? All my siblings have no problem with me living in the house.

Q: Why in Islam you are not allowed to eat or drink with the left hand? Is it mentioend in any hadith?

Q: If Surah Ikhlaas is mistakenly recited in the first Rakaat, what is the best Surah to then recite in the second Rakaat?

Q: My mother died when I was 8-9 months old and my father married another woman and had 2 more sons. But before that, my mother's property was all sold or distributed among many but me. I wasn't given a single portion of the property. And they even kept all this a secret from me till now, I wasn't even told that my real mother had died.

My question is that is this according to Islam, are they right or justified? And Is the selling and distributing of my real mother's property to others without her will (as she died suddenly) right/justified?
