Follow what Allah has taught us .

This hadith talks about how the affairs and religious practices among the Children of Israel were good until a group called Muwalladun emerged. These were children born from female slaves from other nations who began to speak their own opinions in religious matters. As a result they went astray and led others astray as well. This hadith teaches us that it is important to follow what Allah has taught us and not rely on our own opinions or those from outside sources as this can lead us away from the truth. We should always strive to learn more about our faith so that we can stay on the right path and be guided by Allah's teachings only.
