It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both); he said that Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrated to me that the Prophet (peace and blessings be upon him) said: "When Sayyiduna Musa (peace be upon him) met al-Khidr (peace be upon him), a bird came and put its beak into the water. Al-Khidr (peace be upon him) said to Sayyiduna Musa (peace be upon him): Reflect on what this bird is saying. Sayyiduna Musa (peace be upon him) asked: What is it saying? Al-Khidr (peace be upon him) said: This bird is saying that your knowledge and the knowledge of Musa, compared to the knowledge of Allah, is only as much as my beak has taken from this water." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it!

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty: "And their father was a righteous man." [Surah al-Kahf: 82] He said: "The two of them (the orphan boys) were protected because of the righteousness of their father, and no righteousness of their own was mentioned." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.
