Ubaydullah bin Ziyad came to (Sayyiduna) Ma'qil bin Yasar (may Allah be pleased with him) while he was ill, and he said: "Were I not in the throes of death, I would never have narrated to you this saying of the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) said: 'Whoever becomes a guardian of people and does not look after them will not enter Paradise along with them.'"
