Kaab demanded payment from Ibn Abu Hadrad for a debt he owed him, and this took place in the mosque. Their voices grew loud until the Messenger of Allah ﷺ heard them from inside his house. He came out to them and drew back the curtain of his chamber, calling out, "Kaab."Kaab replied, "At your service, Messenger of Allah."The Prophet ﷺ said, "Reduce this debt of yours by this much," gesturing with his hand to indicate half.Kaab said, "I have done so, Messenger of Allah."The Prophet ﷺ then said to Ibn Abu Hadrad, "Get up and pay him."
أنه تقاضى ابن أبي حذرد دينا كان له عليه في المسجد، فارتفعت أصواتهما حتى سمعها رسول الله ﷺ وهو في بيته، فخرج إليهما حتى كشف سجف حجرته فنادى: يا كعب، قال: لبيك يا رسول الله قال: ضع من دينك هذا وأومأ إليه- أي الشطر. قال: لقد فعلت يا رسول الله. قال: قم فاقضه.
Bukhari narrated it in the Book of Prayer (457), and Muslim in the Book of Sharecropping and Farming (1558), both from the hadith of Uthman bin Amr, who said, "Yunus informed us, from Zuhri, from Abdullah bin Kaab bin Malik, from his father," and he mentioned the same, and their wording was identical.
