Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: A man saw a thorny branch on the road and said, "By Allah! I will remove this from the path of the Muslims so that it does not harm them." So Allah, the Exalted, admitted him into Paradise.
`Sayyiduna Abu Barzah (may Allah be pleased with him) says that` I said, "O Prophet of Allah (peace and blessings of Allah be upon him)! Tell me something from which I may benefit." So he (peace and blessings of Allah be upon him) said, "Remove harmful things from the path of the Muslims."
