The intentions of these calls for peace could be deceptive, concealing hidden schemes. If this is their intention, then Allah (swt) is sufficient for you (O’ Muhammad). So long as Allah (swt) is the One Who supports His Messenger (saws), they will not reach him, trick him, or cause any harm to happen through his inclination towards peace, as happened in the Hudaybiyyah Treaty when the Prophet (saws) made peace with Quraysh.

(…هُوَ الَّذِي أَيَّدَكَ بِنَصْرِهِ وَبِالْمُؤْمِنِينَ) (It is He who supported you with His help and with the believers.): So, victory is from Allah (swt), and all these preparations are human means that must be taken. Therefore, one should not say, ‘Allah is sufficient for me, and I rely on Him,’ without taking the necessary measures. This is rejected in Islam. Allah (swt) says in the previous verse: (And prepare against them whatever you are able of power and of steeds of war.).  Anas bin Malik, may Allah be pleased with him, reported that a man said, ‘Oh Messenger of Allah, should I tie it (my camel) and rely on Allah, or should I leave it untied and rely on Allah?’ He (saws) said:

‘Tie it and rely on Allah.’[1]

So, you take the means and rely on the One Who provides the means.”

In this verse Allah says, (It is He who supported you with His help and with the believers.); this is a remarkable strategy: the support of Allah alone is sufficient, so why does Allah (swt) mention the believers? The victory of Allah, the Exalted, comes without any means, as He does not need anyone, glorified be He. However, the presence of the believers alongside the Messenger of Allah (saws) represents the means of achieving victory that Allah (swt) has commanded us to take.
