On the authority of Aboo Dharr who said:

When the Messenger of Allaah left us there was not a bird flapping its wings in the air except that he mentioned to us knowledge about it.
[This is why] the Prophet said:

There does not remain anything that would bring [you] closer to Paradise and farther from the Hell-fire except that it has been [completely] explained to you.
