The texts that described certain actions as disbelief; how do we distinguish between them as to whether they are major shirk or minor shirk?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Some texts describe certain actions as disbelief, so how do we distinguish between them as to whether they are major shirk or minor shirk?

Answer:
What is described as disbelief (kufr), while other texts indicate that it does not take one out of the religion, is minor shirk (associating partners with Allah). Take, for example, killing a soul without right. The Prophet (peace and blessings be upon him) said: So this was described as disbelief, whereas in the verse, "And if two groups among the believers fight," look: This indicates that the killer does not leave the faith. Up to His saying, "Indeed, the believers are brothers." He called them brothers even though they are fighting each other. This indicates that it is minor shirk, not a disbelief that takes one out of the religion. This is the distinction. The second distinction is that they said: If "disbelief" is mentioned with the definite article (al-), it is major shirk; if it is mentioned as an indefinite noun, it is from minor shirk. Yes.
