It is narrated from Sayyiduna Abu Mas'ud (may Allah be pleased with him): When this verse was revealed: "Who is it that will lend Allah a goodly loan" [Surah al-Baqarah: 245], Abu al-Dahdah said: O Messenger of Allah, does Allah want a loan from us? He (peace and blessings be upon him) said: "Yes, O Abu al-Dahdah." He said: Show me your hand. So he (peace and blessings be upon him) gave him his hand. He said: I have lent my orchard to my Lord, and in my orchard there are six hundred date palms. Then he went to the orchard and called out: O Umm al-Dahdah! She was in the orchard, and she said: Labbayk (Here I am). He said: Come out, for I have lent it to my Lord.
