461. Commandment – Prohibition of division into sects

[30:32] Set your face to God, turning to Him in repentance, and fear Him, and observe Prayer, and be not of those who associate partners with God — [30:33] Of those who split up their religion and have become divided into sects; every party rejoicing in what they have.

[3:104] And hold fast, all together, by the rope of Allah and be not divided; and remember the favour of Allah which He bestowed upon you when you were enemies and He united your hearts in love, so that by His grace you became as brothers; and you were on the brink of a pit of fire and He saved you from it. Thus does Allah explain to you His commandments that you may be guided. [3:105] And let there be among you a body of men who should invite to goodness, and enjoin equity and forbid evil. And it is they who shall prosper. [3:106] And be not like those who became divided and who disagreed among themselves after clear proofs had come to them. And it is they for whom there shall be a great punishment,

[4:153] And as for those who believe in Allah and in all of His Messengers and make no distinction between any of them, these are they whom He will soon give their rewards. And Allah is Most Forgiving, Merciful.

[13:22] And those who join what Allah has commanded to be joined, and fear their Lord, and dread the evil reckoning;

[49:11] Surely all believers are brothers. So make peace between brothers, and fear Allah that mercy may be shown to you.

[61:5] Verily, Allah loves those who fight in His cause arrayed in solid ranks, as though they were a strong structure cemented with molten lead.

[42:14] He has prescribed for you the religion which He enjoined on Noah, and which We have revealed to thee, and which We enjoined on Abraham and Moses and Jesus, saying, ‘Remain steadfast in obedience, and be not divided therein. Hard upon the idolaters is that to which thou callest them. Allah chooses for Himself whom He pleases, and guides to Himself him who turns to Him.’

[6:160] As for those who split up their religion and became divided into sects, thou hast no concern at all with them. Surely their case will come before Allah, then will He inform them of what they used to do.
