There is indeed a good model for you in the Messenger of Allah - for the one who has hope in Allah and the Last Day, and remembers Allah profusely.

(6) And when the believers saw the coalition forces, they said, "This is what Allah and His messenger had promised us, and Allah and His messenger had told the truth." And it only increased them in faith and submission. (6). In the context of the battle of Ahzab, this verse is initially meant to remind the hypocrites that they should have followed the example of the Holy Prophet ﷺ who stood firm in the battle, but according to the unique style of the Holy Qur'an, the direction is given in generic terms to lay down a universal rule that the Muslims should follow the examples set by the Holy Prophet ﷺ in all matters of life.

Among the believers, there are men who came true to, the covenant they had with Allah. So, some of them have fulfilled their vows ( by sacrificing their lives in the way of Allah), and some of them are (still) waiting, and they did not change (their commitment) in the least.

(7) (All this happened) so that Allah may give reward to the truthful for their truthfulness, and punish the hypocrites, if He so wills, or accept their repentance. Surely, Allah is Most-Forgiving, Very-Merciful. (7). This verse admires those companions of the Holy Prophet ﷺ who had not participated in the battle of Badr due to some valid excuses, and had vowed that whenever the next battle would come to happen, they would offer their lives in defence of faith. Then, some of them, like Sayyidna 'Anas Ibn Nadr and Mus'ab Ibn ` Umair ؓ fulfilled their vows by sacrificing their lives in the battle of 'Uhud, while some others, like Sayyidna ` Uthman and Talhah ؓ remained alive, but eagerly waiting for having the honor of being martyred in the way of Allah.

And Allah has turned back the disbelievers with all their rage, having achieved no good. And Allah sufficed the believers against fighting.(8) And Allah is Powerful, Mighty.

And He has brought those of the people of the Book who had backed them, down from their fortresses, and cast awe into their hearts, so as to make you kill some of them and take others as captives. (8). It means that Allah made a divine arrangement by sending a violent wind to the coalition forces which compelled them to go back, and thus the Muslims did not have to indulge in a regular battle, except to the extent of some individual encounters.

And He let you inherit their land and their homes and their wealth, and a land you have not trodden (so far). And Allah is Powerful to do anything. (9) (9). These two verses refer to Banu qurayzah, the Jewish tribe who had entered into a treaty with the Muslims not to fight against them, and not to support the enemies of the Muslims. But at the time of the battle of Ahzab, they violated the terms of the treaty and supported the coalition forces. Even earlier, they had been constantly conspiring against the Muslims to an intolerable extent. After the battle of Ahzab was over, the Holy Prophet ﷺ besieged the fortress of Banu qurayzah, and finally, they had to surrender, and most of their men were killed, and the women and children were made captives. This event has been referred to in these verses. At the same time, Allah Ta’ ala has given a good news to the Muslims that they would conquer some other lands which they had not entered before. The words, "and a land you have not trodden" refer to such future victories, especially to the conquest of Khyber that followed within a few years after the battle of Ahzab.

O prophet, say to your wives, "If you intend (to have the pleasure of) worldly life and its charm, then come on, and I shall give you some stuff, and release you in a handsome fashion.

and if you intend (to gain the pleasure of) Allah and His messenger and (the betterment of) the Hereafter, then, Allah has prepared a great reward for those of you who do good".

0 wives of the Prophet, whoever from among you will commit a clearly shameful act, the punishment will be doubled for her. And it is easy for Allah to do so.
