The word(s) "fair-seeming" appears 15 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(11) 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.

(12) Is he, then, to whom the evil of his deeds is made fair-seeming, so that he considers it as good (equal to one who is rightly guided)? Verily, Allah sends astray whom He wills, and guides whom He wills. So destroy not yourself (O Muhammad صلى الله عليه وسلم) in sorrow for them. Truly, Allah is the All-Knower of what they do!

(13) "The ways of the heavens, and I may look upon the Ilah (God) of Musa (Moses): But verily, I think him to be a liar." Thus it was made fair-seeming, in Fir'aun's (Pharaoh) eyes, the evil of his deeds, and he was hindered from the (Right) Path; and the plot of Fir'aun (Pharaoh) led to nothing but loss and destruction (for him).

(14) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. Indeed they (all) were the losers.

(15) "Nay, but you thought that the Messenger (صلى الله عليه وسلم) and the believers would never return to their families, and that was made fair-seeming in your hearts, and you did think an evil thought and you became a useless people going for destruction."
