"He (the Prophet) purchased a calf from a caravan, but he had no money with him. He then sold it with some profit and gave the profit in charity to the poor and widows of Banu 'Abd al-Muttalib. He then said: I shall not buy anything after this but only when I have money with me.
Sunan Abi Dawud Book 23, Hadith 19
← Previous Hadith The Messenger of Allah (ﷺ) would not say funeral prayer over a person who died while the debt was due from him. A dead Muslim was brought to him and he asked: Is there any debt due from him? They (the people) said: Yes, two dirhams. He said: Pray yourselves over your companion.

Then AbuQatadah al-Ansari said: I shall pay them, Messenger of Allah. The Messenger of Allah (ﷺ) then prayed over him.

When Allah granted conquests to the Messenger of Allah (ﷺ), he said: I am nearer to every believer than himself, so if anyone (dies and) leaves a debt, I shall be responsible for paying it; and if anyone leaves property, it goes to his heirs.

Sunan Abi Dawud Book 23, Hadith 18 Next Hadith → The Messenger of Allah (ﷺ) as saying: Delay in payment (of debt) by a rich man is injunctive, but when one of you is referred to a wealthy man, he should accept the reference.
