Importance of the remembrance of Allah.

Reported by Abu Ayyub Al-Ansari (RA): The Prophet (peace be
upon him) said: "He who utters ten times: `La ilaha illallahu,
wahdahu la sharika lahu, lahulmulku wa lahulhamdu, wa
Huwa `ala kulli sha'in Qadir (there is no true god except Allah.
He is One and He has no partner with Him. His is the
sovereignty and His is the praise, and He is Omnipotent),' he
will have a reward equal to that for freeing four slaves from
the progeny of Prophet Isma`il.''[Bukhari & Muslim] Imagine
the huge reward for such a small act!
