Aal-i-Imraan 3:103

And hold fast to the rope of Allah[48] all together and do not be divided. Remember the favor of Allah upon you when you were enemies, then He reconciled your hearts, making you brethren by His grace. And you were on the brink of a fiery pit and He delivered you[49] from it. This is how Allah makes His verses clear to you, so that you may be guided.

[48] The Prophet (ﷺ) said: “I will leave with you after me two grave matters. The first is the Book of Allah. It is the rope of Allah; whoever follows it, is guided and whoever does not, has gone astray”. [Muslim: 2408]
[49] The Prophet (ﷺ) addressed his Anṣār Companions after the Battle of Ḥunayn by saying: “Have I not found you: lost and Allah guided you by me? Destitute and Allah made you well-off by me? Divided and Allah united you by me?” [Muslim: 1061]

And hold firmly to the rope[142] of Allāh all together and do not become divided. And remember the favor of Allāh 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 Allāh make clear to you His verses that you may be guided.

[142] Referring either to His covenant or the Qur’ān.

103. And hold fast, all of you together, to the Rope of Allâh (i.e. this Qur’ân), and be not divided among yourselves[20], and remember Allâh’s Favour on you, for you were enemies one to another but He joined your hearts together, so that, by His Grace, you became brethren (in Islâmic Faith), and you were on the brink of a pit of Fire, and He saved you from it. Thus Allâh makes His Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.,) clear to you, that you may be guided.

[20] (V.3:103) It has been narrated by Abu Hurairah رضي الله عنه in the Hadîth Books (At-Tirmidhi, Ibn Mâjah and Abu Dâwûd) that the Prophet صلى الله عليه وسلم said: "The Jews and Christians were divided into seventy-one or seventy-two religious sects, and this nation will be divided into seventy-three religious sects - all in Hell, except one, and that one is the one on which I and my Companions are today [i.e. following the Qur’ân and the Prophet’s Sunnah (legal ways, orders, acts of worship, statements of the Prophet (صلى الله عليه وسلم)]."

And hold fast, all of you together, to the cable of Allah, and do not separate. And remember Allah's favour unto you: How ye were enemies and He made friendship between your hearts so that ye became as brothers by His grace; and (how) ye were upon the brink of an abyss of fire, and He did save you from it. Thus Allah maketh clear His revelations unto you, that haply ye may be guided,
