It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that there was a time or era among the people when the person most deserving of dirhams and dinars was considered to be one's Muslim brother. Then a time has now come when dirhams and dinars have become more beloved than a Muslim brother. I heard the Prophet (peace and blessings of Allah be upon him) say: "How many neighbors there will be who, on the Day of Resurrection, will cling to their neighbors and say: O my Lord! He closed his door on me and deprived me of his good conduct."
