What is the ruling on boycotting the goods of hostile disbelievers?

Question:
May Allah reward you, Your Eminence, father. The questioner says: From time to time, when the disbelievers commit aggression against Islam and Muslims, some people call for the obligation of boycotting the goods of the disbelievers. Is there any basis for this action in the Book or the Sunnah? Some of them cited the story of the Prophet (peace and blessings be upon him) boycotting the three who lagged behind. Is their citation correct?

Answer:
They lagged behind, not that they lagged behind in the way those who were left behind did. What Allah said was that those who lagged behind—meaning they lagged behind in their command—were not excused in the first instance. Their excuse was delayed until the Qur'an was revealed concerning them. As for the boycott, my brothers, this is part of the state's policy and falls within the authority of the one in authority. If he orders it, we are required to comply. But if he does not order it, a person is free to do as he pleases; if he wants to boycott or not to boycott, it is up to his own desire. If you want, you can never eat or drink again, but no one is coming to force you. Yes.
