Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever witnessed. 78 And pray in the small watches of the morning: (it would be) an additional prayer (or spiritual profit) for thee: soon will thy Lord raise thee to a Station of Praise and Glory! 79 And say [in thy prayer]: "O my Sustainer! Cause me to enter [upon whatever I may do] in a manner true and sincere, and cause me to leave [it] in a manner true and sincere, and grant me, out of Thy grace, sustaining strength!" 80 And say: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 81 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. 82 And when We bestow favours upon man, he turns away and goes far away towards himself; and when evil touches him he despairs. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
