Is my husband entitled to take my salary?
                                Your salary is yours, and you may give some of it to him as a kind of free-will contribution.
                             
                        
                            
                                
                                Is it permissible for the guardian, or the father of the child to hit the latter in order to teach him/her good manners?
                                It is permissible for the guardian to hit his/her child for teaching them good manners once they become ten years old provided that it is done mildly, harmlessly and without intimidation. Actually, such punishment is to be employed gradually i.e. after: asking, warning, and scolding. As for the teacher, he isn`t allowed to hit the student unless the latter`s father approves of it, and it is done according to necessity without intimidation, or harm.
                             
                        
                            
                                
                                Is the one who gives up on marriage because he can`t afford it considered sinful?
                                Marriage is desirable, but one who can`t afford it isn`t considered sinful. However, he should supplicate to Allah, and seek His forgiveness.
                             
                        
                            
                                
                                When Iddah is Initiated for Deceased's Wife?
                                All perfect praise be to Allah, The Lord of The Worlds, and may His Peace and Blessings be upon our Prophet Muhammad and upon all of his family and companions.
Iddah is observed on the same date at which her husband passed away for four months, but as for the pregnant, it is observed at the date she gives birth. And Allah Knows Best.
