Say your prayers from the decline of the sun, until nightfall; and at dawn -- the recitation at dawn is indeed witnessed. 78 Say your special (tahajjud) prayer during some part of the night as an additional (obligatory) prayer for you alone so that perhaps your Lord will raise you to a highly praiseworthy position. 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 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 And We reveal of the Qur'an that which is a healing and a mercy for believers though it increase the evil-doers in naught save ruin. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Proclaim, “Each one works according to his own pattern; and your Lord well knows him who is more upon guidance.” 84
