                                                What should a person who doubted having missed a pillar of prayer do?
                                            
                                            
                                            The Answer : 
                                            
                                                All praise be to Allah, The Lord of The Worlds.                                                                                                                                                                              The prayer of one who doubts having missed one of its pillars is valid, and nothing is due on him/her since having a doubt after offering the act of worship doesn`t undermine its validity. And Allah Knows Best.
