Hadith # 1434
Abu Musa Al-Ash'ari (May Allah be pleased with him) reported: The Prophet (PBUH) said, "The similitude of one who remembers his Rubb and one who does not remember Him, is like that of the living and the dead."
[Al-Bukhari and Muslim]
Commentary
Lack of remembrance of Allah is akin to death. When a person dies, he is unable to do anything. Similarly, a person who does not remember Allah goes so far from Him that he cannot do anything which can benefit him.
