Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) said: Sa'd bin Ubadah (may Allah be pleased with him) said: If I were to see a man with my wife, I would strike him with the sword. This reached the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Are you amazed at the protective jealousy of Sa'd? By Allah, I am more protectively jealous than Sa'd, and Allah is more protectively jealous than me; and because of that He has forbidden shameful deeds - whether open or hidden. And there is no one who loves excuses more than Allah, the Mighty and Majestic; for that reason He sent His messengers as bearers of glad tidings and warners. And there is no one who loves praise more than Allah, the Mighty and Majestic; and for that reason He promised Paradise."
