Hadith 6164
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "When Allah Almighty created Sayyiduna Adam (peace be upon him), he sneezed. His Lord inspired him to say 'Alhamdulillah' (All praise is due to Allah). So his Lord said to him: May Allah have mercy on you. Because of this, Allah's mercy surpassed His wrath."
