What are the two scenes that the Messenger of Allah, peace and blessings be upon him, said about, "No one who witnessed them shall enter the Fire"?

Perhaps the questioner is referring to the hadith narrated by Ibn Majah from Hafsa, who said: The Prophet, peace and blessings be upon him, said: "Indeed, I hope that none of those who witnessed Badr and Hudaybiyah will enter the Hellfire, Allah willing." Ahmad also narrated from Jabir, مرفوعاً (marfu'an, directly attributed to the Prophet): "A man who witnessed Badr and Hudaybiyah will never enter the Hellfire." Al-Albani authenticated it in "Al-Silsilah." Ahmad and Al-Tabarani also narrated from the hadith of Umm Bashir, who said: Hatib's servant came and said: "By Allah, Hatib will not enter Paradise." The Messenger of Allah, peace and blessings be upon him, said: "You lie; he witnessed Badr and Hudaybiyah."
