Establish Prayer from the declining of the sun to the darkness of the night; and hold fast to the recitation of the Qur'an at dawn, for the recitation of the Qur'an at dawn is witnessed. 78 And of the night - keep the vigil therein, as an act of supererogation for thee; belike thy Lord will raise thee up in a station praised. 79 And say: My Lord! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 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 bless man, he turns away, and withdraws aside; but when evil visits him, he is in despair. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
