Teachings of Muhammad صلى الله عليه وسلم
The message revealed to Prophet Muhammad صلى الله عليه وسلم was the same message revealed to all the previous messengers. The central theme of this message was to give people true recognition of their creator and to give them the right direction of life to please Him by worshipping Him and obeying His commandments. Like all messengers, Prophet Muhammad صلى الله عليه وسلم conveyed glad-tidings to the mankind for true belief in Allah سبحانه وتعالى and performing good deeds; and warned them the ill-consequences of the disobedience of Allah سبحانه وتعالى.He taught them what is right and what is wrong and that each action, good or bad, has long lasting consequences in this life and in the life hereafter. He brought the news of the life after death and an everlasting success or failure based upon our performance in this life.
Following the teachings of Prophet Muhammad صلى الله عليه وسلم is a source of pleasure of Allah سبحانه وتعالى and a life full of true belief and good deeds. Ignoring these teachings, on the other hand, would lead to a meaningless life unacceptable by Allah سبحانه وتعالى.
