What is the ruling on the chatting between a young man and his girlfriend?
                                Private chatting between the two sexes entails religious violations, and leads to prohibited attachment.
                             
                        
                            
                                
                                I married a man and had two children; however, we got separated four years ago. In addition, my husband`s brother, paternal uncle of my children, has been providing for them ever since. In fact, he is an honest, well-behaved man. Is it permissible that we get married although his brother (My ex-husband) is still alive?
                                All perfect praise be to Allah the Lord of The Worlds. May His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.
It is temporarily prohibited for a woman to marry her stepbrother. Therefore, once she receives Talaq Ba`in (Irrevocable divorce), she is allowed to marry her stepbrother, even if his brother (First husband) is still alive. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Does passing wind from the anus affect ritual purity?
                                Ablution is nullified by the passing of wind from the anus, but washing the anus is not required as wind leaves no impurity.
                             
                        
                            
                                
                                Is it permissible to fish on Saturday?
                                All Perfect Praise be to Allah, The Lord of The Worlds, and may His Peace and Blessings be upon our Prophet Muhammad and upon all of his family and companions. 
It is permissible for Muslims to fish on any day, but the sons of Israel are the ones forbidden to fish on Saturday. Moreover, there is no evidence in Islamic Sharia prohibiting Muslims from fishing on that day. And Allah Knows Best.
