The Ranks - 61:11
You believe in Allah and His messenger and strive in the way of Allah with your lives and your money. That is best for you, if you only knew.
Following the Qur'an means following the messenger and therefore following Allah:
The Family Of Imran/3:132
Follow Allah and the messenger that you may be merciful.
The Cattle/6:155
And this is a blessed Book which We have sent down. So you should follow it and act righteously so that mercy may be shown to you.
The Women/4:80
He who follows the messenger follows Allah. Whoever turns away, let him turn away; We have not sent you as a watchman over them.
The Light/24:54
"Say, "Obey Allah and the messenger. If you refuse, he is responsible for his duty and you are responsible for yours. If you follow him, you will find the truth. The messenger´s only duty is to make the message clear."
The Poets/26:124
"Their brother Hud said to them, "Will you not act righteously?"
The Poets/26:125
I am a trustworthy messenger sent to you.
The Poets/26:126
Listen to Allah and follow me.
The Coalition/33:36
When Allah and His Apostle judge in a matter, no believing man or woman has a choice in that matter. Whoever disobeys Allah and His messenger has clearly gone astray.
The Pleading Woman/58:8
"Have you not noticed those who were forbidden to hold secret meetings but still persist in what they were forbidden? They are lobbying for the purpose of sinning, enmity and disobeying the Messenger. When they come to you, they greet you in a way that Allah does not greet you. They say among themselves, "Why should Allah punish us for what we say!"Hell is enough for them. There they will burn; what an evil abode is that."
Divorce/65:11
He has sent a messenger. He recites to you the clear signs of Allah to bring those who believe and do righteous deeds out of darkness into light. Whoever believes in Allah and does righteous deeds, He will admit him into Gardens in which rivers flow, where they will abide forever. Allah has given him a goodly sustenance.
