Musnad Ahmad

It is narrated from Hazrat Awf bin Malik (may Allah be pleased with him) that once we were sitting with the Holy Prophet (peace and blessings be upon him) when the Holy Prophet (peace and blessings be upon him) looked towards the sky and then said, "The time for knowledge to be taken away is near." An Ansari man, whose name was Ziyad bin Labid, said, "O Messenger of Allah! Will knowledge be taken away from among us while the Book of Allah is present among us, and we have taught it to our sons and women?" The Holy Prophet (peace and blessings be upon him) said, "I thought you were among the intelligent people of Madinah." Then the Holy Prophet (peace and blessings be upon him) mentioned the misguidance of the People of the Book and that they too had the Book of Allah with them. After this, Jubair bin Nufair met Shaddad bin Aws at the Eidgah, so Jubair narrated this hadith to him from Hazrat Awf (may Allah be pleased with him), and he also confirmed Hazrat Awf's narration and said, "Do you know what is meant by the taking away of knowledge?" I said, "No." He said, "The removal of the vessels of knowledge." Then he asked, "Do you know which knowledge will be taken away first?" I said, "No." He said, "Khushu' (humility and devotion), until you will not see a single person with khushu'."
