Is ablution invalidated when blood comes out of the nose, or a wound?
                                Blood coming out of the nose, or a wound does not invalidate ablution, but it is preferable to make ablution as a way out of the scholars disagreement in this regard.
                             
                        
                            
                                
                                A pious man proposed to me and my father was hesitant in this regard because he is black, am I sinful if I accepted his proposal?
                                If the suitor is pious, color isn`t a drawback. However, try talking to your father kindly, so that he approves of your marriage with contentment, and that is better for you.
                             
                        
                            
                                
                                What is the ruling of Sharia on looking at one`s Mahram women?
                                All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
A Mahram man (man impermissible for a woman to marry) is permitted to look at what usually appears from his Mahram women (women impermissible for a man to marry) while doing their daily housework, with the exception of their private parts. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is a woman`s face an Awrah (a private part) that should be covered?
                                During prayer, a woman`s whole body is a private part except the hands and the face. Outside the time of prayer, scholars are of the view that a woman should wear on her Islamic attire to avoid temptation.
