It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that when this verse was revealed: "You cannot attain the highest level of righteousness until you spend from that which you love," and this verse: "Who is it that will lend Allah a goodly loan," Hazrat Abu Talha (may Allah be pleased with him) said, "O Messenger of Allah (peace and blessings be upon him)! My such-and-such garden which is at such-and-such place, I give it in the name of Allah, and by God! If it were possible for me to keep it hidden, I would never let anyone find out about it." The Prophet (peace and blessings be upon him) said, "Distribute it among the poor of your family."
