Brief Explanation
Benefits: … Allah Ta'ala has used various people to transmit the religion from one generation to another. Among them are also included those who themselves could not benefit from this religion. For example, those scholars who benefit others and establish the rulings of the Shari'ah, but themselves could not act upon their knowledge, or whose purpose was ostentation, showing off, and seeking leadership and authority.
One form of this is that disbelievers and irreligious people oppose Islam, raise objections against Islam, the Qur'an, and the possessor of the Qur'an (sallallahu alayhi wa sallam). As a result, curiosity about Islam and the Qur'an arises in the minds of many disbelievers, and after researching, they accept Islam. (Abdullah Rafiq)
