Translation:

5. Peace!... This until the rise of Morn!

Notes (Tafseer)

6220. When the Night of spiritual darkness is dissipated by the glory of Allah, a wonderful Peace and a sense of Security arise in the soul. And this lasts on until this life closes, and the glorious Day of the new world dawns, when everything will be on a different plane, and the chequered nights and days of this world will be even less than a dream.
