Quiz Orphans' Page Prayer Times Links Islaam. Islam, exactly as it was revealed to Prophet Muhammad, sallallahu alayhe wa sallam, and without any changes or alterations, is the religion that Allah chose for all people from the time he sent His Messenger till the end of time. Islam is thus for recent times just as it was for earlier times. But while the texts of this religion are immutable, people's conditions are not. The texts are divine revelation, but their understanding is a human endeavor.
Divine words are absolute, but their human understanding is relative.
All the Prophet's words and deeds are considered to be a living commentary on the Qur'an. The companions of the Prophet were better placed to do so than later generations because Arabic was their mother tongue, and because they had knowledge of the occasions on which the verses were revealed, and the situations in which the Prophet's words were uttered. Then came generations after generations of great leading scholars whose extant works are a living witness to the fact that they understood the basic meanings of the verses of the Qur'an in generally the same way as they were understood by the first generations. Your claim that each generation gave the words of the Qur'an and those of the Prophet meanings that suited their contemporary cultures is one that history belies. They differed only slightly as far as the basic meanings of the verses and the ahadeeth are concerned.
