It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Near the Day of Judgment, there will be widespread tribulations, killing (harj) will become abundant, and knowledge will be taken away. When Hazrat Umar (may Allah be pleased with him) heard Hazrat Abu Huraira (may Allah be pleased with him) narrating this hadith, he said: Knowledge will not be snatched from the chests of the scholars, rather the scholars themselves will be taken away.
