It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: The Prophet (peace and blessings be upon him) used to teach us that when one of us sneezes, we should respond to his sneeze (with a prayer of mercy).
Al-Tabarani recorded it, and its chain is jayyid (good).
