Combining the hadith "Be the one who is killed" with the hadith "Whoever is killed defending himself"

Question:
(peace and blessings be upon him) used to say: How do we combine the hadith of his saying (peace and blessings be upon him) with the hadith ,

Answer:
Yes, a person defends himself, defends his property, and defends one who attacks his honor. If he is killed, he is a martyr. And if the attacker is killed, the attacker is in the Fire, as the Prophet (peace and blessings be upon him) informed us. This applies in cases other than fitnah (trial, discord or temptation) among Muslims. This is an attacker who attacked you in your house, or attacked you in the open, so you kill him. You repel him with what is best. If he cannot be repelled except by killing him, then kill him. However, if this is in a fitnah (trial, discord or temptation) among Muslims, the best thing is that you do not get involved in it, and you restrain your hand from it. Even if you are killed, you will be, by the permission of Allah, a martyr.
And so did the Companions, or the senior Companions, in the fitnahs (trials, discords or temptations) that occurred: they withdrew from them. Some of them broke their swords, smashed their swords, and prevented their children and those around them from participating in the fitnahs (trials, discords or temptations) that occurred.
