What is the ruling of Sharia when a man releases his sperm out of his wife`s vagina?
                                All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
This is called coitus interruptus and it is permissible according to Sharia when practiced by agreement of both spouses. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is it permissible for a woman to shake hands with her brother-in-law?
                                It is forbidden for the woman to shake hands with her brother-in-law because he isn`t a Mahram (unmarriageable) of hers.
                             
                        
                            
                                
                                Is it allowed for a Muslim woman to wear nail polish?
                                Praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
Nail polish is an adornment that a woman is allowed to wear for her husband, and not in the presence of non-Mahram men. However, during ablution water needs to reach the nails, so it isn`t possible to perform 'Wudu (ablution) with nail polish on. Therefore, it isn`t valid to make Ghusl Jnabah (Ghusl performed after sexual intercourse or ejaculation), Ghusl after menstruation and Ghusl after Nifas (blood of childbirth) while wearing nail polish. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is permissible to include a will requesting that a Holy Qur'an buried along with me?
                                It is not permissible to include a will requesting that a Quran be buried with the deceased in their grave. This is because the body of the deceased typically decomposes and may release impure substances, and it is not allowed to expose the Quran to impurity. Intentionally desecrating the Quran is an act of disbelief. Instead, read the Quran during your lifetime, as it will benefit you after death. And Allah Knows Best.
