Iyas bin Abi Ramlah al-Shami says: I saw Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with him) while he was asking Sayyiduna Zayd bin Arqam (may Allah be pleased with him): Were you present with the Messenger of Allah (peace and blessings be upon him) on an occasion when two Eids (Eid and Friday) came together on a single day? He said: Yes. Mu'awiyah (may Allah be pleased with him) asked: What did he (peace and blessings be upon him) do on that day? He said: He (peace and blessings be upon him) led the Eid prayer and then granted a concession regarding (attendance at) the Friday prayer, and said: "Whoever wishes to pray the Friday prayer, let him pray it." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it. It also has a supporting report (shahid) on the condition of Imam Muslim:

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Two Eids have come together on this day of yours; so for whoever wishes, the Eid prayer will suffice him in place of the Friday prayer, but we will be holding the Friday prayer." This hadith is sahih (authentic) on the condition of Imam Muslim; there is no disagreement about the truthfulness of Baqiyyah bin al-Walid when he narrates from well-known narrators. And it is a gharib (singular) hadith through the narration of Shu'bah, al-Mughirah and Abd al-Aziz, and all of them are narrators whose hadith is collected (for use as evidence).

It is narrated from Sayyiduna Adi bin Hatim (may Allah be pleased with him) that a preacher gave a sermon in the presence of the Prophet (peace and blessings be upon him) and said: "Whoever obeys Allah and His Messenger is rightly guided, and whoever disobeys the two of them (for which he used the dual pronoun) has gone astray." So he (peace and blessings be upon him) said: "Stand up - or he said: go away - what a bad preacher you are." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
