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.
                             
                        
                            
                                
                                Is prayer nullified by having thoughts while performing it?
                                Prayer isn`t nullified by having thoughts while performing it, provided that the praying person offers all of its pillars and meets all of its conditions. However, the reward decreases significantly in the absence of reverence since a praying person is rewarded according to the attentiveness of his/her heart during prayer.
                             
                        
                            
                                
                                What is the ruling on the yellow discharge that comes from a woman during pregnancy?
                                These discharges are not menstrual blood, but they are impure like urine and break the Wudu (ablution). If the discharge is frequent, its ruling is similar to that of urinary incontinence. The woman should perform wudu after the time of each prayer, pray the obligatory prayer, and any additional prayers she wishes, read the Quran, and take precautions against impurity to the best of her ability. Using a special pad can prevent the impurity from spreading. And Allah Knows Best.
                             
                        
                            
                                
                                Should missed Sunnah prayer be made up?
                                Making up missed voluntary acts of worship is from Sunnah.
