The answer: No.
3 – Are the prophet's (PBUH) companions alike? Or some of them are better than the others?
The answer: Allah, the Almighty, made some of them better than the others. The best of them was Abu Bakr Al Seddiq, then Omar Ibn Al Khattab, then Othman Ibn Affan, then Ali Ibn Abu Taleb (may Allah be pleased with them). Allah, the Almighty, said about the prophet's (PBUH) companions: {And why do you not spend in the cause of Allah while to Allah belongs the heritage of the heavens and the earth? Not equal among you are those who spent before the conquest [of Makkah] and fought [and those who did so after it]. Those are greater in degree than they who spent afterwards and fought. But to all Allah has promised the best [reward]. And Allah, with what you do, is Acquainted} (The Iron:10).
4 – If a Jewish or a Christian mother gives her children rights that are not given to others, is this racism and oppression?
The answer: This is neither racism nor oppression, same with Islam, it differentiated between a Muslim and others, Allah the Almighty, says: {Not equal are the companions of the Fire and the companions of Paradise. The companions of Paradise - they are the attainers [of success]} (The Gathering:20).
Third: The prophet's (PBUH) words: "a Muslim shouldn't be killed for killing a disbeliever" don't mean that it's permissible to kill a disbeliever, rather it's prohibited to kill the entrusted, the promised disbeliever, and the people of the book (Jews and Christians). As for the warrior disbeliever, it's permissible to kill him, and this is proved by the following:
1 – Allah, the Almighty, says in the Quran: {Say, "Come, I will recite what your Lord has prohibited to you. [He commands] that you not associate anything with Him, and to parents, good treatment, and do not kill your children out of poverty; We will provide for you and them. And do not approach immoralities - what is apparent of them and what is concealed. And do not kill the soul which Allah has forbidden [to be killed] except by [legal] right. This has He instructed you that you may use reason"} (The Cattle:151).
2 – The speech mentioned in The Correct Bukhari, no, book of (Al Jezia "Capitation"), chapter (the prohibition of killing an entrusted disbeliever without committing a crime), no.2930. Abdullah Ibn Amr (may Allah be pleased with him) narrated that the prophet (PBUH) said: "Whoever killed a person having a treaty with the Muslims, shall not smell the smell of paradise though its smell is perceived from a distance of forty years".
3 – The speech mentioned in Kanz Al Omaal, no. 10909, Soliman Ibn Sard narrated that the prophet (PBUH) said: "If a man trust you for his blood, don't kill him".
Besides, the speech "a Muslim shouldn't be killed for killing a disbeliever" is as same as the speech narrated by Ibn Majah that the prophet (PBUH) said: "A father shouldn't be killed for killing his son".
Now I have a question: Does this mean that it's permissible for a father to kill his son?
The answer: Of course not; Allah, the Almighty, says: {and do not kill your children} (The Cattle:151).
Besides, the prophet's (PBUH) words "a Muslim shouldn't be killed for killing a disbeliever" don't mean that when a Muslim kills a disbeliever (a Jew or a Christian), he shouldn't be punished. Some scholars said that a Muslim who kills a disbeliever by betrayal should be punished by being killed, and by betrayal means a gouger who kills people and steals their money. Al Zuhari narrated from Salem, who narrated from his father that a Muslim killed a man from the people of the book, and was sent to Othman Ibn Affan, who didn't order killing him, but ordered him to pay a huge blood money.
Malek and Al Laith said: If a Muslim kills a disbeliever (a Jew or a Christian), he must be killed in return. (Reference: Nayl Al Awtar, chapter 7, page 154).
