Read all Ahadith in the book on military expeditions by jami al tirmizi

Narrated Abu Al-Bakhtari: An Army from the armies of the Muslims, whose commander was Salman Al-Farisi, besieged one of the Persian castles. They said: 'O Abu 'Abdullah! Should we charge them?' He said: 'Leave me to call them (to Islam) as I heard the Messenger of Allah (ﷺ) call them.' So Salman went to them and said: 'I am only a man from among you, a Persian, and you see that the Arabs obey me. If you become Muslims then you will have the likes of what we have, and from you will be required that which is required from us. If you refuse, and keep your religion, then we will leave you to it, and you will give us the Jizyah from your hands while you are submissive.' He said to them in Persian: 'And you are other than praiseworthy and if you refuse then we will equally resist you.' They said: 'We will not give you the Jizyah, we will fight you instead.' So they said: 'O Abu 'Abdullah! Should we charge them?' He said: 'No.' He said: So for three days he called them to the same (things), and then he said: 'Charge them.' He said: So we charged them, and we conquered the castle.

Narrated Ibn 'Asim Al-Muzani: From his father and he was a Companion who said: When the Messenger of Allah (ﷺ) dispatched any army or battalion, he would say to them: 'If you see a Masjid, or hear someone calling the Adhan, then do not kill anyone.'

Narrated Anas: When the Messenger of Allah (ﷺ) set out for Khaibar, he approached it at night and when he came to a people during the night, he would not attack them until morning. So when the morning came, the Jews came out with their shovels and baskets, then when they saw him, they said: 'Muhammad! By Allah Muhammad has come with the Khamis (an army).' So the Messenger of Allah (ﷺ) said: 'Allahu Akbar! Khaibar is destroyed, for whenever we approach the land of people - then what an evil morning for those who have been warned.'

Narrated Abu Talhah: When the Prophet (ﷺ) overtook a people he would stay at the outskirts of their city for three nights.

Narrated Ibn 'Umar: The Messenger of Allah (ﷺ) burnt the palm trees of Bani Nadir and cut them down at Al-Buwairah. So Allah revealed: Whatever you cut down of their palm trees, or you left them standing on their trunks, then it was by the permission of Allah, and in the order to disgrace the rebellious.(59:5)

Narrated Abu Umamah: That the Prophet (ﷺ) said: Verily, Allah has honored me over the (other) Prophets - or he said: My nation over the nations, and He has made the spoils of war lawful for us.

Narrated Ibn 'Umar: The Messenger of Allah (ﷺ) divided the spoils as two shares for the horse and one share for the man.

Narrated Ibn 'Abbas: That the Messenger of Allah (ﷺ) said: The best companions are four, the best Saraya (military unit) is four hundred, the best army is four thousand, and twelve thousand will not be beaten due to being too few. This Hadith is Hasan Gharib, it was not narrated with a chain by anyone important besides Jarir bin Hazim, and this Hadith was only reported from Az-Zuhri, from the Prophet (ﷺ) in Mursal form. Hibban bin 'Ali Al-'Anazi reported it from 'Uqail, from Az-Zuhri, from 'Ubaidullah, from 'Ibn Abbas, from the Prophet (ﷺ), and Al-Laith bin Sa'd reported it from Sa'd, from 'Uqail, from Az-Zuhri, from the Prophet (ﷺ) in the Mursal form.

Narrated Yazid bin Hurmuz: That Najdah Al-Haruri wrote to Ibn 'Abbas asking if the Messenger of Allah (ﷺ) would fight along with women, and if he would fix a share of the spoils of war for them. Ibn 'Abbas wrote to him: You wrote to me asking me if the Messenger of Allah (ﷺ) would fight along with women. He did fight along with them, as they would treat the wounded. They received something from the spoils of war, but as for their share, then he did not fix a share for them. There is something on this topic from Anas and Umm 'Atiyyah. This Hadith is Hasan Sahih. This is acted upon according to most of the people of knowledge. It is the view of Sufyan Ath-Thawri and Ash-Shafi'i. Some of them said that a share is given to the woman and the boy, and this is the view of Al-Awza'i. Al-Awza'i said: The Prophet (ﷺ) gave a portion to the boys at Khaibar, and the Aimmah of the Muslims gave a portion to every child born in the land of war. Al-Awza'i said: The Prophet (ﷺ) gave a portion to the women at Khaibar, and that was followed by the Muslims after him. This was narrated to us by 'Ali bin Khashram (who said): 'Eisa bin Yunus narrated this to us from Al-Awza'i. The meaning of his saying: They received something from the spoils of war it is said that he conferred something on them (the women) from the spoils of war.

Narrated 'Umair, the freed slave of Abil-Lahm: I participated at Khaibar with my masters. They spoke about me to the Messenger of Allah (ﷺ) and told him that I was a slave. He said: So he ordered me to take up the sword, and I found myself dragging it, so he ordered that I be given something from the goods. I presented a Ruqyah that I used to treat the possessed with, so he ordered me leave some of it and keep some of it. There is something on this topic from Ibn 'Abbas. This Hadith is Hasan Sahih. This is acted upon according to the some of the people of knowledge. A complete portion is not given to slave, but something is conferred upon him. This is the view of Ath-Thawri, Ash-Shafi'i, Ahmad, and Ishaq.
