Āl ‘Imrān

إِنَّ الَّذِينَ اشْتَرَوُاْ الْكُفْرَ بِالإِيمَانِ لَن يَضُرُّواْ اللّهَ شَيْئًا وَلهُمْ عَذَابٌ أَلِيمٌ

177. "Verily those who have bought infidelity for faith, never shall they harm Allah at all; and they will have a painful torment."

The subjects of buying and selling, and also gaining and losing, have frequently been repeated through different occurrences in the Qur'an. In this process, the Qur'an is considered as a market, where people are the sellers, the beliefs and thoughts are the goods, and sometimes Allah and sometimes other than Allah are the customers. In this market selling is compulsory, but electing the customers is up to the choice of human beings. That is, we cannot leave out what we have, including power, action, and belief, but we can set our belief and action in a path to be gainful or detrimental.

In the Qur'an, those who purchase with Allah and take Heaven and His pleasure in return, are praised, while another group are criticized. This group, for their perversion or for choosing gain, either do not make profit:

or face with loss:

Surah Al-Hajj, No.22, verse 11 And, in some verses, of the Qur'an like the above verse, those who sell their Faith in return with infidelity are despised, and, on the other side, the believers are consoled that the apostasy of that group has no harm to Allah or to the path of Allah.
