The best type of believer is one who makes their own choices about belief and is willing to fight for their right to do so. The definition of a believer is "a person who believes that a specified thing is effective, appropriate, or desirable" or "someone who has faith in something or someone." Faith can be classified in three different ways. The first is legitimate faith. Legitimate faith is when someone believes what is true.

Do not believe in traditions because they have been passed down for many generations.

It is said: “Fight and kill the pagans wherever you find them, seize them, besiege them and lie in wait for them in all stratagems (of war). " Muhammad said in the Hadith: "The person who participates in (sacred fights) for the cause of Allah and nothing obliges him to do so except belief in Allah and His Messenger, will be rewarded by Allah either by a reward, or loot (if he survives). or will be admitted to Paradise (if he is killed). When he started preaching Islam in Mecca, Allah told him to fight the People of the Book (Christians and Jews) because they do not accept the truth (Islam).).
