Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.

As a Muslim, we believe that the Bible comprising of both the Old and the New Testaments which is read and circulated among Jews and Christian is not the original Bible which has been revealed to Moses (peace be upon him) and Jesus.

It includes many distortions and blasphemous statements about Allah and His Messengers.

Selling those books to non-Muslims falls within the prohibition which is expressed in the following verse of the Quran:

“And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah ; indeed, Allah is severe in penalty.” (Al-Ma’idah 5:2)

The Prophet, moreover, used to obliterate crosses, according to the following ḥadith: `A’ishah said, “I never used to leave in the Prophet (peace be upon him) house anything carrying images or crosses but he obliterated it.” (Al-Bukhari)

Those crosses which were drawn on clothes have been obliterated by the Prophet because they refer to a false claim which has been condemned and falsified by the Quran, i.e. crucifixion of Jesus. The same ruling is extended to other materials or books which propagate for false creeds and deviant views which misguide people.

Almighty Allah knows best.
