Ali said, "There was a time, or he said a period, when none of us considered himself more entitled to his dinar and dirham than his Muslim brother. Now, however, the dinar and the dirham are dearer to one of us than his Muslim brother. I heard the Prophet ﷺ say, 'How many a neighbor will cling to his neighbor on the Day of Resurrection, saying, My Lord, this man shut his door against me and withheld his kindness from me.'"
لقد أتى علينا زمان- أو قال: حين- وما أحد أحق بديناره ودرهمه من أخيه المسلم، ثم الآن الدينار والدرهم أحب إلى أحدنا من أخيه المسلم، سمعت النبي ﷺ يقول: كم من جار متعلق بجاره يوم القيامة، يقول: يا رب! هذا أغلق بابه دوني، فمنع معروفه.
Bukhari narrated it in Adab al-Mufrad (111) from Malik bin Ismail, who said, Abdul-Salam narrated to us, from Layth, from Nafi, from Ibn Umar, who said, and then he mentioned it.Layth here is Ibn Abu Salim, not Layth bin Saad. Although Layth bin Saad also narrates from Nafi, Abdul-Salam bin Harb is among those who narrate from Layth bin Abu Salim. Layth bin Abu Salim has been criticized regarding his memory, but he has a corroborating narration.Ibn Abu Dunya narrated it in Makarim Akhlaq (345) through the route of Musa bin Khalaf Ammi, Aban narrated to us, from Ataa, from Ibn Umar, who said, and he mentioned something similar.Aban here is Ibn Bashir Muktib, from whom Khalaf bin Khalifa, Wahb bin Baqiya, and Musa bin Khalaf Ammi narrated. Ibn Hibban mentioned him among the trustworthy narrators, while Ibn Abu Hatim said, "Unknown," as recorded in Lisan Mizan, meaning his status is unknown.Through this chain of transmission, the hadith rises to the level of hasan.
