Fourth: it brings expansion to the heart. When a person gives something—especially wealth—he finds a sense of openness within himself. This is something well established through experience, provided that he gives generously and willingly, rather than giving while his heart remains attached to what he has given.
Ibn al-Qayyim mentioned in Zād al-Maʿād (1) that giving and generosity are among the causes of expansion of the heart. Yet only the one who gives generously and willingly benefits from this: the one who removes the wealth from his heart before removing it from his hand. As for one who removes the wealth from his hand while it remains deep within his heart, he will not benefit from such giving.
Fifth: it raises a person to the rank of the complete believer: “None of you truly believes until he loves for his brother what he loves for himself” (2). Just as you would love for someone to give you the wealth by which you can meet your need, you should love to give it to your brother. By doing so, you attain completeness of faith.
Sixth: it is among the means of entering Paradise. Indeed, Paradise is for “the one who speaks kindly, spreads greetings of peace, feeds others, and prays at night while people are asleep” (3). And all of us strive to enter Paradise.
