God says
…And pay heed unto God and His Apostle so that you might be graced with mercy. And vie with one another to attain your Sustainer’s forgiveness and a paradise as vast as heavens and the earth, which has been readied for the God-conscious -- Q.3:132, 132
He who obeys the Apostle obeys God thereby;… Q.4:80
O mankind! The Apostle has now come to you with the truth* from your Sustainer: believe, then, for your own good!.And if you deny the truth – behold, unto God belongs all that is in the heavens and all that is on earth, and God is indeed all-knowing, wise! -- Q.4:170
* Man is sent down on Earth with a definite purpose, with his faculties, intelligence, freedom of decision provided. In addition, the book of knowledge and wisdom, the Quran, to inform him of the purpose; to guide through life’s this phase of performance and actions; to tell of its next phase of reward and punishment.
Several things we try to do daily on their appointed time. Why not accord affordable time for understanding the truth that has been conveyed through our Prophet who must be obeyed. It is the Message for us from our Sustainer to be understood over and over again so as to act upon it. This is the only chance we have!
Now whenever God and His Apostle have decided a matter,* it is not for a believing man or a believing woman to claim freedom of choice insofar as they themselves are concerned: for he who [thus] rebels against God and His Apostle has already, most obviously, gone astray. -- Q.33:36
* I.e., Whenever a specific law has been formulated as such in the Quran or in an injunction promulgated by the Prophet.
Prophet said
“…the best guidance is the guidance of Muhammad.” -- H: Muslim
