Question :
                                            
                                            
                                            
                                                Does passing wind, from the anus without a smell, invalidate prayer?
                                            
                                            
                                            The Answer : 
                                            
                                                If a person is certain of having passed wind even if it was with no smell, then both his/her ablution and prayer are invalidated, thus he/she should remake ablution and re-perform prayer.
