Tafsir of Al-Mursalat 77:25

أَلَمْ نَجْعَلِ الْأَرْ‌ضَ كِفَاتًا أَحْيَاءً وَأَمْوَاتًا (Did We not make the earth a container that collects the living and the dead?....25, 26) The word kit is derived from kaft. It means 'to gather things together'. Thus kit is a thing that embodies many things within itself. Earth is created by Allah in a fashion that humans when alive, remain on its back, and when dead, in its belly.
