It is He Who takes you back to Himself (yatawaffakum) at night, while knowing the things you perpetrate by day, and then wakes you up again, so that a specified term may be fulfilled. Then you will return to Him. Then He will inform you about what you did. (Surat al-An’am: 60)
The word used for "take back" in this verse is the same as the one used in Surah Al ‘Imran 55. In other words, in both verses, the word "tawaffa" is used and it is obvious that one does not die in one’s sleep. Therefore, what is meant here is, again, "taking the self back."
