The ruling on the hadith "like scattered dust" and an explanation of showing off in worship

Question:
The questioner says: Honorable Shaykh, may Allah grant you success. It is reported from the Messenger (peace and blessings be upon him) that on the Day of Resurrection, some people will come with good deeds like mountains, and Allah will turn them into scattered dust. Does this hadith apply only to the hypocrites, or to everyone who commits forbidden acts?

Answer:
These people have wronged others. They come with good deeds and they come with wrongs, so on the Day of Resurrection, the wronged are compensated from their good deeds, and nothing remains for them, and nothing remains for them. Also, the hadith indicates that whoever does not make his intention sincere for Allah the Exalted in his work, his work becomes scattered dust. Whoever does not make his intention sincere, his work is scattered dust. Therefore, the one who fights in the battle and is killed while seeking praise and wanting to be called brave, this person is dragged into the Fire on the Day of Resurrection, because this is showing off in worship. And the one who gives charity with money and wants to be praised and called generous, this is the first one to be dragged into the Fire on the Day of Resurrection. And the one who recites the Qur'an and teaches knowledge so that he is called a scholar, this is the first one to be dragged into the Fire, may Allah protect us from that, because he is showing off in his work, as came in the authentic hadith.
Yes. The first three to be set ablaze by the Fire are: a fighter who seeks showing off in worship, a giver of charity who seeks showing off in worship, and a learner who seeks showing off in worship and praise. Yes.
