It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "You are in a time in which scholars are many and preachers are few. Whoever abandons even a tenth of his knowledge in this time will be destroyed. Soon there will come a time upon the people in which scholars will be few and preachers will be many. In that time, whoever acts upon even a tenth of his knowledge will attain salvation."
