Surah 8. Al-Anfal
Ayah 61 - 63
61 وَإِن جَنَحُوا۟ لِلسَّلْمِ فَٱجْنَحْ لَهَا وَتَوَكَّلْ عَلَى ٱللَّهِ ۚ إِنَّهُۥ هُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ
62 وَإِن يُرِيدُوٓا۟ أَن يَخْدَعُوكَ فَإِنَّ حَسْبَكَ ٱللَّهُ ۚ هُوَ ٱلَّذِىٓ أَيَّدَكَ بِنَصْرِهِۦ وَبِٱلْمُؤْمِنِينَ
63 وَأَلَّفَ بَيْنَ قُلُوبِهِمْ ۚ لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ وَلَـٰكِنَّ ٱللَّهَ أَلَّفَ بَيْنَهُمْ ۚ إِنَّهُۥ عَزِيزٌ حَكِيمٌ
61. But if they incline to peace, you also incline to it, and trust in Allah. Verily, He is the All-Hearer, the All-Knower. 62. And if they intend to deceive you, then verily, Allah is All-Sufficient for you. He it is Who has supported you with His help and with the believers. 63. And He has united their (believers') hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allah has united them. Certainly He is All-Mighty, All-Wise.
Allah says, if you fear betrayal from a clan of people, then sever the peace treaty with them, so that you both are on equal terms. If they continue being hostile and opposing you, then fight them,
(But if they incline), and seek,
(to peace), if they resort to reconciliation, and seek a treaty of non-hostility,
(you also incline to it), and accept offers of peace from them. This is why when the pagans inclined to peace in the year of Hudaybiyah and sought cessation of hostilities for nine years, between them and the Messenger of Allah he accepted this from them, as well as, accepting other terms of peace they brought forth. `Abdullah bin Al-Imam Ahmad recorded that `Ali bin Abi Talib said that the Messenger of Allah said,
(There will be disputes after me, so if you have a way to end them in peace, then do so.)
Allah said next,
(and trust in Allah. ) Allah says, conduct a peace treaty with those who incline to peace, and trust in Allah. Verily, Allah will suffice for you and aid you even if they resort to peace as a trick, so that they gather and reorganize their forces,
(then verily, Allah is All-Sufficient for you).
Allah mentioned His favor on the Prophet , in that He aided him with believers, the Muhajirin and the Ansar,
(He it is Who has supported you with His help and with the believers. And He has united their hearts.)
The Ayah says, `it is Allah who gathered the believers' hearts, believing, obeying, aiding and supporting you -- O Muhammad,'
(If you had spent all that is in the earth, you could not have united their hearts.) because of the enmity and hatred that existed between them. Before Islam, there were many wars between the Ansar tribes of Aws and Khazraj, and there were many causes to stir unrest between them. However, Allah ended all that evil with the light of faith,
(And remember Allah's favor on you, for you were enemies one to another, but He united your hearts, so that, by His grace, you became brethren, and you were on the brink of a pit of Fire, and He saved you from it. Thus Allah makes His Ayat clear to you, that you may be guided.) ﴿3:103﴾
In the Two Sahihs, it is recorded that when the Messenger of Allah gave a speech to the Ansar about the division of war booty collected in the battle of Hunayn, he said to them,
(O Ansar! Did I not find you misguided and Allah guided you by me, poor and Allah enriched you by me, and divided and Allah united you by me) Every question the Prophet asked them, they said, "Truly, the favor is from Allah and His Messenger.'' Allah said,
(But Allah has united them. Certainly He is All-Mighty, All-Wise.)
He is the Most Formidable, and the hopes of those who have trust in Him, never end unanswered; Allah is All-Wise in all of His decisions and actions.
