Surah 78. An-Naba, Ayah 11

According to Zamakhshari, the term ma'ash ("that whereby one lives") is here synonymous with "life". In the polarity of sleep (or "death") and wakefulness (or "life") we see the allusion to bodily death and subsequent resurrection already touched upon in 6:60 .

"Subsistence" in English only partly covers the idea of ma'ash, which includes every kind of life activity. The Day is specially illuminated, so runs the figure of speech, in order that these life-activities of all kinds may be fully exercised.
