"They are the ones who say: Do not spend on those who are with the Messenger of Allah until they disperse." The Tafsir of al-Kalbi states: It was revealed concerning Abdullah ibn Ubayy ibn Salul, the leader of the hypocrites, for he said to a group of people who were spending on some of those who were with the Messenger of Allah (peace be upon him): Do not spend on them until they disperse from him. His saying: "And to Allah belong the treasures of the heavens and the earth," means: the knowledge of the treasures of the heavens and the earth.
