﴿ وَلَقَدْ أَرْسَلْنَا نُوحًۭا وَإِبْرَٰهِيمَ وَجَعَلْنَا فِى ذُرِّيَّتِهِمَا ٱلنُّبُوَّةَ وَٱلْكِتَٰبَ ۖ فَمِنْهُم مُّهْتَدٍۢ ۖ وَكَثِيرٌۭ مِّنْهُمْ فَٰسِقُونَ ﴾

“And, indeed, [to the same end] We sent forth Noah and Abraham [as Our message-bearers], and established prophethood and revelation among their descendants; and some of them were on the right way, but many were iniquitous.”

All the prophets who came here on behalf of God brought the same religion. But successive generations, introduced innovations in the name of the prophet. An example of this is found in the followers of Jesus. Jesus was entrusted only with the task of conveying the Truth. His prophetic responsibilities did not include fighting. So, he laid more emphasis on missionary ethics, such as are based entirely on affection and compassion. He advised his followers to be affectionate and compassionate towards others. But after Jesus his followers could not fully appreciate this point. By temperament they tended towards renunciation. For the purpose of missionary work, they were only advised not to be engrossed in purely worldly considerations, but they went to the extreme of renouncing the world.
