Says the Shaykh Abu Ja'far: Our belief concerning this is that Allah has undoubtedly created man with a disposition towards (accepting) the unity of Allah2. And this is (in consonance with) what He, the Mighty and Glorious, says:
“The true faith of Allah, for the acceptance of which He has created man” (Qur'an 30:30).3
And concerning His saying, exalted is He:
“It is not for Allah to lead a people astray after He hath rightly guided them, until He hath clearly shewn to them what they ought to fear” (Qur'an 9:116).
Imam Ja'far as-Sadiq4 said: (He does not lead them astray) until He informs them of what pleases and what displeases Him. And concerning the saying of Him, who is exalted above all:
“And (He) inspired it5 (with the consciousness of) what is wrong for it and what is right for it,” (Qur'an 91:8),
he (Imam Ja'far) said: (That means) He made manifest to it (the soul) what (acts) are permissible and what sins are to be avoided. And He, Exalted is He, says:
“Verily We have shown him the way, whether he be grateful or disbelieving” (Qur'an 76:3),
and (concerning this) he (Imam Ja'far) said: (That is) We have made it (the true religion) known to him, whether he accepts it or not.
And concerning the saying of Him, who is mighty and Glorious:
“And as for Thamud, We gave them guidance, but they preferred blindness to guidance” (Qur'an 41:17).
Imam Ja'far explained: (And this) despite their knowing (the truth). Imam Ja'far as-Sadiq was asked concerning the saying of Allah, the Mighty and Glorious:
“And (did We not) guide him to the parting of the two mountain paths?” (Qur'an 90:10).
He said: (This refers to) the path of righteousness and the path of wickedness. And he said: That which Allah has kept from the knowledge of human beings is entirely set apart from them. And he also said: Allah has adduced reasons to mankind for what He has given them and what He has made known to them.6
