The Cattle - 6:153
This is my straight path. Follow it and do not follow other ways, for they will lead you away from His Way. These are His admonitions to you that you may listen.
What we must follow, what we must obey:
The Companies/39:55
Follow the best teaching sent down to you from your Lord, before the torment seizes you suddenly when you do not expect it.
The Companies/39:56
"So that he may not say, "Woe to me for disregarding the teaching of Allah; indeed, I was one of the mockers"
The Companies/39:57
"Or say, "Had Allah guided me to the truth, I would certainly have been one of the righteous."
The Companies/39:58
"Or when he sees the torment, let him not say, "If only I had had a second chance, I would have been of the righteous"
The Heights/7:157
Indeed, they follow (when the time comes) that messenger whom they find written in the Torah and the Gospel with them, the Messenger of Allah, the Messenger of the Ummim (who has not read the Torah and the Gospel), who enjoins upon them good and forbids them from evil, who makes lawful for them good things and forbids for them unclean things, who removes from them the weights and the fetters that weigh them down. Those who believe in him and respect him and help him and follow the light sent down with him are the successful ones.
The Heights/7:3
Follow what has been sent down to you from your Lord, and do not follow others besides Him as your friends. How little do you take admonition!
The Coalition/33:2
Follow what has been revealed to you from your Lord. Allah is aware of all that you do.
The Cattle/6:106
Follow what has been sent down to you from your Lord. There is no god but Him. And turn away from those who associate partners.
The Ornaments of Gold/43:43
Hold fast to what has been revealed to you, for you are on the right path.
