Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Your smiling at your brother is also charity." (Imam Ibn Hibban, may Allah have mercy on him, says:) The narrator named Abu Zumail is Simak bin Waleed Hanafi Yamani, and he is trustworthy, while the narrator named Nasr bin Muhammad is Jurashi Yamani, and Nadr bin Muhammad is Quraishi Marwazi, who was a man of opinion, and both of them lived in the same era.
