What is the context of revelation for this āyah?

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. The verse was revealed concerning ʿAmr ibn al-Jamūḥ al-Anṣārī, who had a great deal of wealth. He asked: "O Messenger of Allah, what should we give in charity, and upon whom should we spend?" So, this verse was revealed. [Abū Ṣāliḥ from Ibn ʿAbbās]
2. A man said to the Prophet (ﷺ), "I have a dinar." The Prophet replied: "Spend it on yourself." The man said, "I have two." The Prophet said: "Spend them on your family." The man said, "I have three." The Prophet said: "Spend them on your servant." The man said, "I have four." The Prophet said: "Spend them on your parents." The man said, "I have five." The Prophet said: "Spend them on your relatives." The man said, "I have six." The Prophet replied: "Spend them in the way of Allah, which is the best of them." So, this verse was revealed. [ʿAṭāʾ from Ibn ʿAbbās]
