A man cursed Allah, is he allowed to perform prayer without making Ghusl?
                                All perfect praise be to Allah the Lord of the Worlds. May Allah`s peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
 
Cursing Allah is an act of apostasy and one who commits it must utter the testimonies of faith, make repentance, take back wife; however, it isn`t conditioned that he makes Ghusl (Full body ritual purification) to pray. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is it permissible for us to sever ties of kinship if our blood-relatives` gatherings/meetings involve acts of sin?
                                Observing kinship ties is obligatory, and paying your blood-relatives a visit causing their sinful acts to be hindered , then you should do so. However, if their sinful acts continue while you are at their gathering and they didn't respond positively, then observing kinship ties via telephone and the like will suffice in this case. And Allah Knows 
                             
                        
                            
                                
                                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.
                             
                        
                            
                                
                                Is it permissible to listen to chants praising the Prophet if accompanied by musical instruments?
                                If singing, or chanting in praise of the Prophet was accompanied by a forbidden musical instrument, then it is forbidden.
