Silsilah as-Sahihah 2788 — Rights of one Muslim over another

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, who says that the Messenger of Allah, peace and blessings be upon him, said: “A Muslim has five rights over another Muslim: returning the greeting of peace, accepting an invitation, following funeral processions, visiting the sick, and responding to the sneeze of one who sneezes, provided he says «اَلْحَمْدُ لِلّٰهِ».”
