(Ashoora) 42 : 13
شَرَعَ لَكُمْ مِنَ الدِّينِ مَا وَصَّىٰ بِهِ نُوحًا وَالَّذِي أَوْحَيْنَا إِلَيْكَ وَمَا وَصَّيْنَا بِهِ إِبْرَاهِيمَ وَمُوسَىٰ وَعِيسَىٰ ۖ أَنْ أَقِيمُوا الدِّينَ وَلَا تَتَفَرَّقُوا فِيهِ ۚ كَبُرَ عَلَى الْمُشْرِكِينَ مَا تَدْعُوهُمْ إِلَيْهِ ۚ اللَّهُ يَجْتَبِي إِلَيْهِ مَنْ يَشَاءُ وَيَهْدِي إِلَيْهِ مَنْ يُنِيبُ

It is ordained to you from the religion with what was Noah enjoined, and what We have inspired in to you, and with what We have made enjoin in to Ibrahim, Moses and Jesus; You have to establish the religion, and you shouldn’t differentiate in it, to what you are calling the Mushriks is intolerable upon them, Allah chooses in to Him whom He wishes; and whoever turns to Him, Allah guides him.

The Messengers mentioned in this verse Noah, Ibrahim, Moses, Jesus and Muhammed are known as ‘Ulul Azm’ which means ‘who are endowed with firm heart’. This verse reminds and commands the believers that the Dheen-life way-of all Messengers was same and that was the life way Adhikr-the Truth and Guidance-submits, and you should retain that life way, and you shouldn’t make any differentiation in it. But the Fujjar who have become Mushriks by differentiating in to different organization in the label of Islam as explained in verses 23: 51-53 and 30: 31-32, and by associating others in the dominion of Allah are included in the party of Satan as explained in verse 58: 19. They are rejecting not only the command of this verse, but the command of Lord’s Book as a whole.
‘Allah chooses in to Him whom He wishes’ means Allah chooses Messengers from mankind to invite the mankind to Him. ‘Whoever turns to Him, Allah guides him’ means whoever turns to Allah, who is the owner of the Soul whom Adhikr submits, He guides such believer in to Him. Lord Allah has taught through His Messenger in his farewell pilgrimage that whoever holdfasts the Splendid Book Adhikr with his molar tooth, such are only guided and are in the Straightpath. See explanation 3: 19, 101-103; 13: 27, and 42: 2-3.
