This hadith has been transmitted on the authority of Sahl b. Sa'd as-Sa'idi with a slight variation of wording.
The Prophet Muhammad ﷺ said that generosity is a sign of faithfulness and kindness is a sign of nobility; both qualities are essential for living a good life according to Islamic teachings. He also said that when you give something away with an open heart, Allah will reward you with something better in return - this could be material or spiritual rewards such as peace of mind or inner contentment. Therefore it is important for Muslims to practice generosity and kindness on a daily basis in order for them reap these rewards from Allah SWT .
