Hadith 4241
Khaitamah reports: We were sitting with Sayyiduna Abdullah bin Amr (may Allah be pleased with them) when his scribe came to him. Sayyiduna Abdullah (may Allah be pleased with him) asked: Have you given the slaves their food? He replied: No. So Sayyiduna Abdullah (may Allah be pleased with him) said: Go and give it to them, because the Prophet (peace and blessings of Allah be upon him) said: It is enough of a sin for a man that he does not fulfill the rights of those whose sustenance is his responsibility.
