Sahih Muslim Hadith 3764
English
[3764] 17 – (1499) It was narrated that Al-Mughirah bin Shu'bah said: "Sa'd bin 'Ubâdah said: 'If I saw a man with my wife, I would strike him with my sword, and not with the flat side of it.' News of that reached the Messenger of Allah and he said: 'Are you surprised at the jealousy of Sa'd? By Allah, I am more jealous than him, and Allah is more jealous than me. It is because of His jealousy that Allah forbade immoral deeds, both open and secret. There is no person who is more jealous than Allah, and there is no person to whom warnings are more beloved than Allah. Because of that, Allah sent the Messengers as bearers of glad tidings and warnings. There is no person to whom praise is more beloved than Allah. Because of that Allah made the promise of Paradise."
