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 during a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory. 79 Say: "O my Lord! Let my entry be by the Gate of Truth and Honour, and likewise my exit by the Gate of Truth and Honour; and grant me from Thy Presence an authority to aid (me)." 80 And say: "The truth has now come [to light,] and falsehood has withered away: for, behold, all falsehood is bound to wither away!" 81 And We send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except in loss. 82 And when We bless man, he turns away, and withdraws aside; but when evil visits him, he is in despair. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
