The wives of Allah's Apostle (ﷺ) sent Fatima, the daughter of Allah's Messenger (ﷺ), to Allah's Apostle (ﷺ). She sought permission to get in as he had been lying with me in my mantle. He gave her permission and she said: Allah's Messenger, verily, your wives have sent me to you in order to ask you to observe equity in case of the daughter of Abu Quhafa. She (`A'isha) said: I kept quiet. Thereupon Allah's Messenger (ﷺ) said to her (Fatima): O daughter, don't you love whom I love? She said: Yes, (I do). Thereupon he said: I love this one. Fatima then stood up as she heard this from Allah's Messenger (ﷺ) and went to the wives of Allah's Apostle (ﷺ) and informed them of what she had said to him and what Allah's messenger (ﷺ) had said to her. Thereupon they said to her: We think that you have been of no avail to us. You may again go to Allah's Messenger (ﷺ) and tell him that his wives seek equity in case of the daughter of Abu Quhafa. Fatima said: By Allah, I will never talk to him about this matter. `A'isha (further) reported: The wives of Allah's Apostle (ﷺ) then sent Zainab b. Jahsh, the wife of Allah's Apostle (ﷺ), and she was one who was somewhat equal in rank with me in the eyes of Allah's Messenger (ﷺ) and I have never seen a woman more advanced in religious piety than Zainab, more God-conscious, more truthful, more alive to the ties of blood, more generous and having more sense of self-sacrifice in practical life and having more charitable disposition and thus more close to God, the Exalted, than her. She, however, lost temper very soon but was soon calm. Allah's Messenger (ﷺ) permitted her to enter as she (`A'isha) was along with Allah's Messenger (ﷺ) in her mantle, in the same very state when Fatima had entered. She said: Allah's Messenger, your wives have sent me to you seeking equity in case of the daughter of Abu Quhafa. She then came to me and showed harshness to me and I was seeing the eyes of Allah's Messenger (ﷺ) whether he would permit me. Zainab went on until I came to know that Allah's Messenger (ﷺ) would not disapprove if I retorted. Then I exchanged hot words until I made her quiet. Thereupon Allah's Messenger (ﷺ) smiled and said: She is the daughter of Abu Bakr.
Sahih Muslim Book 44, Hadith 120
"We were in a Roman city, when a large column of Romans came out to us. So about the same number or more of the Muslims went towards them. The commander of the people of Egypt was 'Uqbah bin 'Amir, and the commenter of the (our) group was Fadalah bin 'Ubaid. One man among the Muslims reached the Roman line until he entered amidst them, so the people started screaming: 'Subhan Allah! He has thrown himself into destruction!' Abu Ayyub Al-Ansari said: 'O you people! You give this interpretation for this Ayah, while this Ayah was only revealed about us, the people among the Ansar, when Allah made Islam might, and increased its supporters. Some of us secretly said to each other, outside of the presence of the Messenger of Allah (ﷺ): "Our wealth has been ruined, and Allah has strengthened Islam, and increased its supporters, so if we tend to our wealth then what we lost of it shall be revitalized for us." So Allah, Blessed and Most High, revealed to His Prophet (ﷺ), rebuking what we said: 'And spend in the cause of Allah, and do not throw yourselves into destruction. (2:195)' So the destruction was tending to the wealth and maintaining it.' Abu Ayyub did not cease traveling in Allah's cause, until he was buried in the land of the Romans."
Jami` at-Tirmidhi Book 47, Hadith 24
One who defected from obedience (to the Amir) and separated from the main body of the Muslims - if he died in that state-would die the death of one belonging to the days of Jahiliyya (i.e. would not die as a Muslim). One who fights under the banner of a people who are blind (to the cause for which they are fighting, i.e. do not know whether their cause is just or otherwise), who gets flared up with family pride, calls (people) to fight for their family honour, and supports his kith and kin (i.e. fights not for the cause of Allah but for the sake of this family or tribe) - if he is killed (in this fight), he dies as one belonging to the days of Jahiliyya. Whoso attacks my Ummah (indiscriminately) killing the righteous and the wicked of them, sparing not (even) those staunch in faith and fulfilling not his promise made with those who have been given a pledge of security - he has nothing to do with me and I have nothing to do with him.
