The Journey to Allah: A explanation of the Hadith "Your actions alone will not save any of you."

Bukhari records on the authority of Abu Hurayrah that the Prophet (Peace and blessings be upon him)said, "Your actions alone will not save any of you." They asked, 'Messenger of Allah, not even you?' He replied, "Not even me, unless Allah were to envelop me in His mercy. Be firm; steadfast and balanced; and journey [to Allah] in the beggining of the day, at the end of the day, and a portion of the latter part of the night. Moderation, moderation! Through this you will obtain this goal!"
