Tidur itu adalah kematian sementara

Quote from the Holy Quran (39 - 42)

الله يتوفى الأنفس حين موتها والتي لم تمت في منامها ۖ فيمسك التي قضى عليها الموت ويرسل الأخرى إلى أجل مسمى ۚ إن في ذلك لآيات لقوم يتفكرون

Allahu yatawaffa alanfusa heena mawtiha waallatee lam tamut fee manamiha fayumsiku allatee qada AAalayha almawta wayursilu alokhra ila ajalin musamman inna fee thalika laayatin liqawmin yatafakkaroona

It is Allah Who takes away the souls at the time of their death, and those that die not during their sleep. He keeps those (souls) for which He has ordained death and sends the rest for a term appointed. Verily, in this are signs for a people who think deeply.
