It was narrated that Abu Umamah said:
"The Messenger of Allah said: 'You must acquire this knowledge before it is taken away, and its taking away means that it will be lifted up.' He joined his middle finger and the one that next to the thumb like this, and said: 'The scholar and the seeker of knowledge will share the reward, and there is no good in the rest of the people.'"
