It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Allah Almighty has permitted me to tell you about a (gigantic) rooster whose feet are on the earth and whose neck is bent beneath the Throne. It says (in glorification): 'Subhanaka, ma a'zama rabbana!' (O Allah, You are free of all imperfection; how great is our Lord!) Then Allah Almighty replies: The one who swears falsely by Me does not know this (My greatness)." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

Sa'd bin Ubaydah narrates that Sayyiduna Ibn Umar (may Allah be pleased with them both) heard a man swearing by the Ka'bah, so he said: Do not swear by the Ka'bah, for I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever swears by other than Allah has committed disbelief - or (he said) has committed shirk." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyidah Qutaylah bint Sayfi (may Allah be pleased with her), a woman of the tribe of Juhaynah, that a Jewish scholar (habr) came to the Prophet (peace and blessings be upon him) and said: You people also commit shirk. You say: 'Ma sha'a Allahu wa shi'ta' (What Allah wills and what you (peace and blessings be upon him) will), and you swear 'by the Ka'bah'. So the Messenger of Allah (peace and blessings be upon him) said (to the Companions): 'Ma sha'a Allahu thumma shi'ta' "Say it this way: What Allah wills, then what you will; and if you must swear, say: By the Lord of the Ka'bah." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Buraydah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "He is not one of us who swears by 'the trust' (al-amanah), and he too is not one of us who incites a man's wife or his slave (against her husband or his master)." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
