Salim bin Amir reports that there was a treaty for a certain period between Muawiyah (may Allah be pleased with him) and the Romans. Muawiyah (may Allah be pleased with him) used to go towards their cities so that when the term of the treaty expired, he could attack them. Suddenly, he saw a man on his mount or horse saying: "Allahu Akbar! You should fulfill the covenant on your part, not break it." That man was Amr bin Abasah (may Allah be pleased with him). So Muawiyah (may Allah be pleased with him) asked him about this, and he said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'If there is a treaty between a man and a people, he should not break the treaty or make a new one until its term has expired or he returns it to them on equal terms.'" Muawiyah (may Allah be pleased with him) then returned with the people. Imam Tirmidhi says:
This hadith is Hasan Sahih.

‘Abdullah bin ‘Umar (may Allah be pleased with them) says: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say:“Indeed, for every betrayer, a flag will be set up for him on the Day of Resurrection.” Imam Tirmidhi says:
1- This hadith is hasan sahih.
2- I asked Muhammad about this hadith of Suwaid, which he narrates from Abu Ishaq Sabi’i, from Abu Ishaq from ‘Ammarah bin ‘Umair, from ‘Ammarah from ‘Ali (may Allah be pleased with him), and ‘Ali (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him), that he said:“For every covenant-breaker there will be a flag.”Muhammad bin Isma’il al-Bukhari said: To my knowledge, this hadith is not marfu’.
3- In this chapter, there are also ahadith from ‘Ali, ‘Abdullah bin Mas’ud, Abu Sa’id al-Khudri, and Anas (may Allah be pleased with them).

Jabir (may Allah be pleased with him) reports that during the Battle of Ahzab, Sa’d bin Mu’adh (may Allah be pleased with him) was struck by an arrow; the disbelievers had cut his Akhil or Abjal vein (a vein in the arm). The Messenger of Allah (peace and blessings of Allah be upon him) cauterized it with fire, so his hand swelled, and thus he left it. Then the blood began to flow again, so he cauterized it again, and his hand swelled. When Sa’d bin Mu’adh (may Allah be pleased with him) saw this, he prayed:“O Allah! Do not take my soul until my eyes are cooled by (witnessing) the destruction and humiliation of Banu Qurayzah.”So his vein stopped bleeding, and not a single drop of blood dripped from it, until Banu Qurayzah descended (from their fortress) at the command of Sa’d bin Mu’adh (may Allah be pleased with him). The Messenger of Allah (peace and blessings of Allah be upon him) called Sa’d, and he came and judged that their men should be killed and their women kept alive so that the Muslims could benefit from their service. __QUR_N__ The Messenger of Allah (peace and blessings of Allah be upon him) said:“You have judged concerning them with the judgment of Allah.”Their number was four hundred. When he finished with their execution, Sa’d’s vein opened and he passed away. __QUR_N__ Imam Tirmidhi says:
1- This hadith is Hasan Sahih (good and authentic).
2- In this chapter, there are also ahadith from Abu Sa’id Khudri and Atiyyah Qurazi (may Allah be pleased with them both).

Samurah bin Jundub (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "Kill the men among the polytheists and leave those of their boys who have not reached the age of puberty." «شرخ» Those boys are the ones who have not grown pubic hair. Imam Tirmidhi says:
1- This hadith is Hasan Sahih Gharib,
2- Hajjaj bin Arta’ah has narrated a similar hadith from Qatadah.

‘Atiyyah Qarazi (may Allah be pleased with him) says: We were presented before the Prophet (peace and blessings of Allah be upon him) on the day of Qurayzah, so whoever had (pubic) hair grown was killed, and whoever did not have it was let go. I was among those who did not have hair, so I was let go. Imam Tirmidhi says:
1- This hadith is hasan sahih,
2- Some people of knowledge act upon this; if puberty and age are not known, they consider the appearance of (pubic) hair as a sign of puberty. This is also the view of Ahmad and Ishaq bin Rahwayh.

'Abdullah bin Amr (may Allah be pleased with them both) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said in his sermon: "Fulfill the alliances (pacts of cooperation) of the pre-Islamic era, for they only strengthen Islam, and do not make any new pact of cooperation in Islam." __QUR_N__ Imam Tirmidhi says:
1- This hadith is Hasan Sahih,
2- In this chapter, hadiths have also been narrated from Abdur Rahman bin Awf, Umm Salamah, Jubair bin Mut'im, Abu Hurairah, Ibn Abbas, and Qais bin Asim (may Allah be pleased with them all).

Bajalah bin Abadah says: I was the scribe of Juz’ bin Mu’awiyah at the place of Manazir. A letter from ‘Umar (may Allah be pleased with him) came to us, stating:“Look for the Magians (Zoroastrians) among you and take jizyah from them, because ‘Abdur-Rahman bin ‘Awf (may Allah be pleased with him) informed me that the Messenger of Allah (peace and blessings be upon him) took jizyah from the Magians of Hajar.”__REF_N__

Imam Tirmidhi says: This hadith is Hasan.

It is narrated from Bajalah bin Abda that Umar (may Allah be pleased with him) did not take jizyah from the Magians until Abdur Rahman bin Awf (may Allah be pleased with him) informed him that the Prophet (peace and blessings of Allah be upon him) had taken jizyah from the Magians of Hajar. There is more detail in this hadith. Imam Tirmidhi says:
This hadith is Hasan Sahih.

Sa’ib bin Yazid (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) took jizya from the Magians of Bahrain, and ‘Umar and ‘Uthman (may Allah be pleased with them both) took jizya from the Magians of Persia. Imam Tirmidhi says:
I asked Muhammad bin Isma’il Bukhari about this hadith, and he informed me that Malik narrates from Zuhri, and Zuhri narrates from the Prophet (peace and blessings of Allah be upon him).

'Uqbah bin 'Amir (may Allah be pleased with him) says: I submitted, "O Messenger of Allah! We pass by people who neither host us nor fulfill the right that is due to us, and we do not take anything from them." The Messenger of Allah (peace and blessings of Allah be upon him) said: "If they do not give except that you take from them by force, then take it by force." Imam Tirmidhi says:
1- This hadith is Hasan (good).
2- It has also been narrated by Layth bin Sa'd from Yazid bin Abi Habib (as is in the chain of Bukhari).
3- The meaning of this hadith is that when the Companions would go out for jihad, they would pass by a people where they would not find food to buy at a price. The Prophet (peace and blessings of Allah be upon him) said: "If they refuse to sell (food) except that you take it by force, then take it by force."
4- In another hadith, a similar clarification has come. It is narrated from 'Umar bin Khattab (may Allah be pleased with him), he also used to give a similar ruling. 1
