(111) Verily, those who believe not in the Hereafter, We have made their deeds fair-seeming to them, so that they wander about blindly.

(112) "I found her and her people worshipping the sun instead of Allah, and Shaitan (Satan) has made their deeds fair-seeming to them, and has barred them from (Allah's) Way: so they have no guidance."

(113) And the heart of the mother of Musa (Moses) became empty [from every thought, except the thought of Musa (Moses)]. She was very near to disclose his (case, i.e. the child is her son), had We not strengthened her heart (with faith), so that she might remain as one of the believers.

(114) And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukm (Prophethood and right judgement of the affairs) and religious knowledge [of the religion of his forefathers i.e. Islamic Monotheism]. And thus do We reward the Muhsinun (i.e. good doers. See the footnote of V.9:120).

(115) Those who believe [in the Oneness of Allah (Monotheism) and in Messenger Muhammad صلى الله عليه وسلم , and do not give up their faith because of the harm they receive from the polytheists], and do righteous good deeds, surely, We shall expiate from them their evil deeds and shall reward them according to the best of that which they used to do.

(116) And for those who believe (in the Oneness of Allah and the other articles of faith) and do righteous good deeds, surely, We shall make them enter with (in the entrance of) the righteous (in Paradise).

(117) And 'Ad and Thamud (people)! And indeed (their destruction) is clearly apparent to you from their (ruined) dwellings. Shaitan (Satan) made their deeds fair-seeming to them, and turned them away from the (Right) Path, though they were intelligent.

(118) And when they embark on a ship, they invoke Allah, making their faith pure for Him only: but when He brings them safely to land, behold, they give a share of their worship to others .

(119) (It is) a Promise of Allah (i.e. Allah will give victory to the Romans against the Persians), and Allah fails not in His Promise, but most of men know not.

(120) And those who have been bestowed with knowledge and faith will say: "Indeed you have stayed according to the Decree of Allah, until the Day of Resurrection: so this is the Day of Resurrection, but you knew not."
