How can the hadith, "The first people to be thrown into the Hellfire on the Day of Resurrection" (a reciter, a mujahid, and a charitable person who did it for show), be reconciled with Abu Hurairah's hadith, "The first three to enter the Hellfire" (a ruler, a wealthy person, and a proud poor person)?

The hadith "Indeed, the first of people to be judged on the Day of Resurrection will be a man who was martyred..." is an authentic hadith narrated by Muslim. It indicates that the first to be held accountable on the Day of Resurrection will be the martyr, the seeker of knowledge, and the one who spends [in charity], whose deeds were not sincerely for the sake of Allah, but rather sought reputation and praise, so they will be dragged to the Fire. As for the hadith "The first three to enter Paradise and the first three to enter Hell were shown to me...", it is weak due to its chain of narration, whose narrators are unknown. A weak hadith cannot contradict an authentic and established hadith.
