Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: A man came to the service of the Prophet Muhammad (peace and blessings be upon him); he wanted to go on a journey. He greeted the Prophet (peace and blessings be upon him) with salam. The Prophet (peace and blessings be upon him) said: I advise you to adopt the fear of Allah Almighty and to say "Allahu Akbar" (Allah is the Greatest) upon every elevation you ascend. The narrator says: When that man left, the Prophet (peace and blessings be upon him) prayed: O Allah! Fold the earth for him and make his journey easy for him.
