Sura 6 Aya 125

Translator	Translation
Ali Quli Qara'i	Whomever Allah desires to guide, He opens his breast to Islam, and whomever He desires to lead astray, He makes his breast narrow and straitened as if he were climbing to a height. Thus does Allah lay [spiritual] defilement on those who do not have faith.
Pickthal	And whomsoever it is Allah's will to guide, He expandeth his bosom unto the Surrender, and whomsoever it is His Will to send astray, He maketh his bosom close and narrow as if he were engaged in sheer ascent. Thus Allah layeth ignominy upon those who believe not.
Shakir	Therefore (for) whomsoever Allah intends that He would guide him aright, He expands his breast for Islam, and (for) whomsoever He intends that He should cause him to err, He makes his breast strait and narrow as though he were ascending upwards; thus does Allah lay uncleanness on those who do not believe.
Yusufali	Those whom Allah (in His plan) willeth to guide,- He openeth their breast to Islam; those whom He willeth to leave straying,- He maketh their breast close and constricted, as if they had to climb up to the skies: thus doth Allah (heap) the penalty on those who refuse to believe.
