It is narrated from Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) that a man who used to go to his father's wife was mentioned to Sayyiduna Sa'd bin Ubadah (may Allah be pleased with him), and he said: If I had found him, I would have struck him with my sword. I mentioned this to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "I have more protective jealousy (ghayrah) than Sa'd, and Allah has more protective jealousy than I. No one loves excuse (repentance and apology) more than Allah; for that reason He sent the messengers. And no one loves praise of Himself more than Allah; for that reason He promised Paradise." This hadith has an authentic chain (sahih al-isnad), and Imam Abu Awanah explicitly named this client (mawla) of al-Mughirah in his narration and brought the text in its proper form.

It is narrated from Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) that Sayyiduna 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, not with its flat side but with its edge. When this reached the Messenger of Allah (peace and blessings be upon him), he (peace and blessings be upon him) said: "Are you amazed at Sa'd's protective jealousy? By Allah! I have more protective jealousy than he, and Allah has more than I. Because of this very jealousy of Allah, He has forbidden all shameful deeds, whether open or hidden. No one has more protective jealousy than Allah, and no one loves excuse (the servant's repentance) more than Allah; for that reason He sent the messengers as bearers of good news and as warners. And no one loves praise of Himself more than Allah; for that reason He promised Paradise."

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "O young men of Quraysh! Do not commit fornication. Take heed! Whoever guards his private parts, Paradise is for him." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him): Abu al-Darda (may Allah be pleased with him) and I were with the Prophet (peace and blessings be upon him), and I heard him (peace and blessings be upon him) say: "Whoever guards what is between his two jaws (fuqmayhi) and between his two legs has entered Paradise."

The same narration is also reported through another chain, in which the narrator's name is given as Aqil.
