Perform As-Salat (Iqamat-as-Salat) from mid-day till the darkness of the night (i.e. the Zuhr, 'Asr, Maghrib, and 'Isha' prayers), and recite the Quran in the early dawn (i.e. the morning prayer). Verily, the recitation of the Quran in the early dawn is ever witnessed (attended by the angels in charge of mankind of the day and the night). 78 And as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 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 disappeared. Falsehood is always bound to wither away." 81 We reveal the Quran which is a cure and mercy for the believers but does nothing for the unjust except to lead them to perdition. 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 one acts according to his disposition, but your Lord knows well who follow the right path." 84
