It is your father’s duty to force him to pray. If he insists on not praying, he may kick him out of the house and disown him! He is an adult and is accountable for his actions and it is  up to him to pray or not!

I want to ask you about something very important which is, my brother is almost 21 years old and he mostly does not pray and we have tried with him with everything but no reaction. We don’t know what to do! And I want to know will Allah punish mom because her son does not pray?

Is it true that sins fall down from our shoulders during ruku and sujood positions?

I have 3 questions:1) i was born in mauritius but i now live in the UK as im married there and work there. I do travel to Mauritius every year for about six weeks. Do i need to perform all the rakaahs of all namaz or does safar apply to me? 2) is it haraam to change our name to that of our husband’s after we get married as it will be imitating the kaafir?
