Is it permissible for a praying person to make supplication in each Sajdah (a prostration) of obligatory prayer?
                                It is permissible for a praying person, whether praying individually, or in congregation, to make supplication during Sujood (prostration) in obligatory, or voluntary prayers. However, it is disliked for the Imam to do so since he is required to spare the prayer performers any sort of hardship, unless he is leading a certain group who don`t mind him extending the prayer.
                             
                        
                            
                                
                                Should missed Sunnah prayer be made up?
                                Making up missed voluntary acts of worship is from Sunnah.
                             
                        
                            
                                
                                I`m a pious Muslim woman, but my husband isn`t, what should I do?
                                You should exercise patience, make supplication that Allah guides him to the straight path, and keep advising him kindly.
                             
                        
                            
                                
                                What is the expiation for perjury?
                                One who commits perjury should repent, seek Allah`s forgiveness and offer an expiation which is: feeding ten indigent persons, or clothing them, or giving a slave his freedom, but if that is beyond his means then, he should fast for three days. Allah, The Almighty, Says in this regard (What means): "Allah will not call you to account for what is futile in your oaths, but He will call you to account for your deliberate oaths: for expiation, feed ten indigent persons, on a scale of the average for the food of your families; or clothe them; or give a slave his freedom. If that is beyond your means, fast for three days. That is the expiation for the oaths ye have sworn. But keep to your oaths. Thus doth Allah make clear to you His signs, that ye may be grateful."
