From the writings of the Promised Messiah as the Founder of the Ahmadiyya Muslim Jamaat:

“In order to become recipient of the blessings and Grace of God the Almighty it is very essential that one must have a clean heart. Nothing can be gained without it. What is really required is that when God peeps into the heart of the man, there should be no iota of hypocrisy in any nook and corner. It is only this state of the heart which attracts the Manifestation of God – and that makes the relations between God and man, very straight forward. For all this, one must be loyal and sincere as Hazrat Ibrahim [Abraham], peace be upon him, was; also, as the Holy Prophet, sallallaho alaihi wa sallam was. When a man walks on their footsteps he becomes a blessed man and is saved from every kind of humiliation; he is also provided amply and his circumstances are never straitened. Rather the doors of the Grace of God are opened for him and he joins the group of the people whose prayers are accepted by God. Such a person never dies the death of an accursed person; his end is always good.

In short, whoever is sincere and loyal to God, he is granted all his wishes – and he does not come across any disappointment.” (Malfoozat vol. 6, pg. 376)
