There is no day on which Allah frees more servants from the Fire than the day of Arafah

It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "There is no day on which Allah Almighty frees servants from the Fire in such great numbers as the day of Arafah. He draws near (in a manner befitting His majesty), then boasts before the angels, saying: What do these people want?"
The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Sayyiduna Sa'id bin Jubayr (may Allah have mercy on him) that: We were with Sayyiduna Ibn Abbas (may Allah be pleased with them both) at Arafah, and he asked me: O Sa'id, why is it that I do not hear the people reciting the talbiyah? I said: They are afraid of Mu'awiyah (may Allah be pleased with him). So Ibn Abbas (may Allah be pleased with them both) came out of his tent and called aloud: 'Labbayka Allahumma labbayk' (Here I am, O Allah, here I am). Then he said: These people have abandoned the Sunnah out of hatred for Sayyiduna Ali (may Allah be pleased with him).
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) stood at Arafat, and when he (peace and blessings be upon him) said 'Labbayka Allahumma labbayk' (Here I am, O Allah, here I am), he also said: "Indeed, the true good is only the good of the Hereafter."
Imam Bukhari used Ikrimah as evidence and Imam Muslim used Dawud as evidence, and this hadith is sahih (authentic), but the two Shaykhs did not record it.
