Abu Idris al-A'idhi said: I came to Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) and he said: I will narrate what I heard from the blessed tongue of the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) said: "My love is due to those who love one another for My sake; My love is due to those who maintain ties with one another for My sake; My love is due to those who sit together in rows (gather together) for My pleasure; and My love is due to those who spend on one another for My sake."
