Should nail polish be removed before making ablution?
                                Yes, it should be removed because it prevents water from reaching the nails.
                             
                        
                            
                                
                                Is it permissible for a person to give the Zakah (obligatory charity) to his daughter-in-law?
                                Yes, it is permissible for a person to give the Zakah to his daughter-in-law if she was poor, and none provided for particularly by whom are obliged to provide for her. And Allah Knows Best.
                             
                        
                            
                                
                                What is the ruling of Sharia on having an injection to stop the menses considering the fact that she is a challenged person?
                                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.
We recommend visiting a skilled doctor who fears Allah. If he says that there is no harm in having the injection, then it is permissible to use it. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is it permissible to make ablution without answering the call of nature after waking up?
                                Washing front and back openings (Istinjaa`) is not a condition for the validity of ablution because it is done to remove Najaasah (impurity), thus if there is no Najaasah, there is no need for that, and then it is permissible to make ablution without answering the call of nature. However, prayer is invalidated if there is Najaasah on the anus ,or the front opening, so it (Najaasah) must be removed for the prayer to become valid, and not the ablution.
