The Ruling on One Who Curses the Companions and Casts Aspersions on the Mother of the Believers, A'ishah

Question:
What is the ruling on those who exaggerate in their praise of some of the Companions and belittle others, even cursing some of the Companions and accusing the Mother of the Believers of zina (unlawful sexual intercourse)?

Answer:
The Companions (may Allah be pleased with them) are the elite of the Ummah, the best of the Ummah, and the Salaf (the earliest generations) of the Ummah. Whoever slanders them is slandering Islam, for they are the ones who transmitted Islam to us from the Messenger (peace and blessings be upon him). They are the link between us and the Messenger (peace and blessings be upon him). They are the ones who supported the Messenger and fought alongside him, sacrificing their lives and wealth for him. They are the ones who spread Islam after the death of the Messenger (peace and blessings be upon him) to the East and the West. They are the ones who taught humanity, teaching them the beneficial knowledge they inherited from the Messenger (peace and blessings be upon him). So who is this person who loves them?
And the Messenger (peace and blessings be upon him) said: your soul is in His hand, if you gave in charity as much gold as Mount Uhud, it would not equal the reward of a Companion if he gave in charity a mudd (a quarter of a sa') of food or half a mudd, due to their virtue and their status. And whoever does not exonerate A'ishah (may Allah be pleased with her) from what Allah has exonerated her from is a liar against Allah and His support and the consensus of the Muslims, so he is a disbeliever, and I seek refuge in Allah. Yes.
