22:78
وَ جَٰهِدُ وا۟ فِى ٱللَّهِ حَقَّ جِهَادِ هِۦ هُوَ ٱجْتَبَىٰ كُمْ وَ مَا جَعَلَ عَلَيْ كُمْ فِى ٱل دِّينِ مِنْ حَرَجٍ مِّلَّةَ أَبِي كُمْ إِبْرَٰهِيمَ هُوَ سَمَّىٰ كُمُ ٱلْ مُسْلِمِينَ مِن قَبْلُ وَ فِى هَٰذَا لِ يَكُونَ ٱل رَّسُولُ شَهِيدًا عَلَيْ كُمْ وَ تَكُونُ وا۟ شُهَدَآءَ عَلَى ٱل نَّاسِ فَ أَقِيمُ وا۟ ٱل صَّلَوٰةَ وَ ءَاتُ وا۟ ٱل زَّكَوٰةَ وَ ٱعْتَصِمُ وا۟ بِ ٱللَّهِ هُوَ مَوْلَىٰ كُمْ فَ نِعْمَ ٱلْ مَوْلَىٰ وَ نِعْمَ ٱل نَّصِيرُ
And strive for Allah with the striving due to Him. He has chosen you and has not placed upon you in the religion any difficulty. [It is] the religion of your father, Abraham. Allah named you "Muslims" before [in former scriptures] and in this [revelation] that the Messenger may be a witness over you and you may be witnesses over the people. So establish prayer and give zakah and hold fast to Allah. He is your protector; and excellent is the protector, and excellent is the helper.
3:101
وَ كَيْفَ تَكْفُرُ ونَ وَ أَنتُمْ تُتْلَىٰ عَلَيْ كُمْ ءَايَٰتُ ٱللَّهِ وَ فِي كُمْ رَسُولُ هُۥ وَ مَن يَعْتَصِم بِ ٱللَّهِ فَ قَدْ هُدِىَ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ
And how could you disbelieve while to you are being recited the verses of Allah and among you is His Messenger? And whoever holds firmly to Allah has [indeed] been guided to a straight path.
3:103
وَ ٱعْتَصِمُ وا۟ بِ حَبْلِ ٱللَّهِ جَمِيعًا وَ لَا تَفَرَّقُ وا۟ وَ ٱذْكُرُ وا۟ نِعْمَتَ ٱللَّهِ عَلَيْ كُمْ إِذْ كُن تُمْ أَعْدَآءً فَ أَلَّفَ بَيْنَ قُلُوبِ كُمْ فَ أَصْبَحْ تُم بِ نِعْمَتِ هِۦٓ إِخْوَٰنًا وَ كُن تُمْ عَلَىٰ شَفَا حُفْرَةٍ مِّنَ ٱل نَّارِ فَ أَنقَذَ كُم مِّنْ هَا كَ ذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَ كُمْ ءَايَٰتِ هِۦ لَعَلَّ كُمْ تَهْتَدُ ونَ
And hold firmly to the rope of Allah all together and do not become divided. And remember the favor of Allah upon you - when you were enemies and He brought your hearts together and you became, by His favor, brothers. And you were on the edge of a pit of the Fire, and He saved you from it. Thus does Allah make clear to you His verses that you may be guided.
4:146
إِلَّا ٱلَّذِينَ تَابُ وا۟ وَ أَصْلَحُ وا۟ وَ ٱعْتَصَمُ وا۟ بِ ٱللَّهِ وَ أَخْلَصُ وا۟ دِينَ هُمْ لِ لَّهِ فَ أُو۟لَٰٓئِكَ مَعَ ٱلْ مُؤْمِنِينَ وَ سَوْفَ يُؤْتِ ٱللَّهُ ٱلْ مُؤْمِنِينَ أَجْرًا عَظِيمًا
Except for those who repent, correct themselves, hold fast to Allah, and are sincere in their religion for Allah, for those will be with the believers. And Allah is going to give the believers a great reward.
4:175
فَ أَمَّا ٱلَّذِينَ ءَامَنُ وا۟ بِ ٱللَّهِ وَ ٱعْتَصَمُ وا۟ بِ هِۦ فَ سَ يُدْخِلُ هُمْ فِى رَحْمَةٍ مِّنْ هُ وَ فَضْلٍ وَ يَهْدِي هِمْ إِلَيْ هِ صِرَٰطًا مُّسْتَقِيمًا
So those who believe in Allah and hold fast to Him - He will admit them to mercy from Himself and bounty and guide them to Himself on a straight path.
