It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him), he says: I presented myself before the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, command me to do an action that will admit me to Paradise. The Messenger of Allah (peace and blessings be upon him) said: Observe fasting, for there is no other deed like it. When I came to him again and made the same request, the Messenger of Allah (peace and blessings be upon him) said: Observe fasting.
