The most prominent issues derived from the chapter: Instructing the dying person and the ruling on one who says "La ilaha illa Allah"

Question:
Honorable Shaykh, we would like to conclude this session and this great chapter, O Shaykh. We want to extract the most prominent issues derived from this lesson, may Allah preserve you.

Answer:
The most prominent issues derived are the emphasis on instructing the dying person to say "La ilaha illa Allah," even if he is a mushrik (one who associates partners with Allah) or a disbeliever. He is to be instructed to say "La ilaha illa Allah" at the time of death, for if he dies with it as his last word, he will enter Paradise, be saved from the Fire, and deserve the intercession of those who intercede from among the people of knowledge and the people of righteousness. It is a great word that yields great benefits. When, in some of the military expeditions, there was Usamah ibn Zayd (may Allah be pleased with him), who was the beloved of the Messenger of Allah (peace and blessings be upon him), they caught a man to kill him, and he said, "La ilaha illa Allah." So Usamah raised his sword and killed him; he killed him after he had said "La ilaha illa Allah." When the Prophet (peace and blessings be upon him) was informed of this, he was angry with Usamah. He said, "Did you kill him after he said 'La ilaha illa Allah'?" He said, "O Messenger of Allah, he only said it to ward off the sword." He said, "Why did you not cut open his chest to know whether he said it to ward off the sword? Why did you not cut open his chest?" This indicates that one who says "La ilaha illa Allah" is to be spared, and he is to be judged as a Muslim until it becomes clear from him something that contradicts this word, in which case he is to be judged as an apostate. Yes.
