Surah 32. As-Sajdah, Ayah 16

Lit., "whose sides [i.e., bodies] restlessly rise".

Men and women "breathless with adoration" shun soft, comfortable beds, and luxurious sleep. Their limbs are better exercised in offices of devotion and prayer, especially by night. Commentators specially refer this to Prayers called Tahajjud, which are offered after midnight in the small hours of the morning.

In Fear and Hope: in spiritual fear lest their dedication to Allah should not be sufficiently worthy to be accepted, and a spiritual longing or hope that their shortcomings will be overlooked by the Mercy of Allah. And their adoration is not shown only in Prayer, but also in practical Service and Charity, out of whatever gifts they may have received from Allah.
