Is Zakah (obligatory charity) due on the items used in the trading process such as: cars , shops etc..?
                                No Zakah is due on equipments used in the trading process such as cars and the like.
                             
                        
                            
                                
                                Does the deceased hear the supplications or recitations of those visiting his/her grave? And does making constant supplications for the deceased who didn`t adhere to performing the prescribed prayers ameliorate his/her affliction?
                                Praise be to Allah the Lord of the Worlds.
In principle, the dead hear the living since it has been rigorously authenticated that the Prophet (PBUH) ordered the bodies of the idolaters slain in the Battle of Badr to be buried. He then approached them and called them one by one and said: "Have you found what your Lord promised to be true for we have found what our Lord promised us to be true." Umar asked him: "O messenger of God! Why do you speak to lifeless bodies?" The Prophet (PBUH) replied: "By the One Who has sent me with the truth! You do not hear my words better than they do except that they cannot respond." [Agreed upon].
However, not all the deceased are in the same situation because Allah The Almighty Knows: "Before them is a Partition till the Day they are raised up." [Al-Mu`minun/100]. Moreover, supplication reaches the deceased. And Allah Knows Best..
 
                             
                        
                            
                                
                                Is Fajr (dawn) Sunnah a confirmed one?
                                All praise be to Allah The Lord of The Worlds                                                                                                                                                                                  Of course, it is a confirmed Sunna which the Prophet (PBUH) used to offer in a regular basis. And Allah Knows Best.
                             
                        
                            
                                
                                What is the ruling on working in the construction project of an Islamic bank`s administration building?
                                All perfect 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  There is no sin in working for the bank that declares compliance with the rulings of Sharia, in addition to adhering to the rulings of the supervising Sharia committee in the bank itself. This is provided that the committee consists of righteous, trustworthy, specialized scholars. And Allah The Almighty Knows Best.
