It is narrated from Sayyiduna Abu Barzah (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "My Pool is (as wide as) the distance between Aylah and San'a'. Its breadth is equal to its length. Two spouts pour into it from Paradise, one of silver and the other of gold. Its water is sweeter than honey, colder than snow, whiter than milk and softer than butter. On it are jugs as many as the stars of the sky. Whoever drinks from it will never feel thirst until he enters Paradise." The narrator said that Ayyub added in this narration: "They (the cups) will leap of their own accord into the hands of the believers." This hadith is sahih (authentic) on the condition of Muslim, because he used two hadiths of Abu Talhah al-Rasibi as evidence; and this narration of Ayyub al-Sakhtiyani is gharib (singular) and sahih, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "You are not even one part in a hundred thousand of those who will come to me at the Pool." People asked him: How many were you (at that time)? He said: Eight hundred or nine hundred. Imam Bukhari used Abu Hamzah al-Ansari (Talhah bin Yazid) as evidence.

It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "You are not even one part in a hundred thousand of those who will come to me at the Pool on the Day of Resurrection." The narrator said: We asked Zayd (may Allah be pleased with him): How many were you that day? He said: Between six hundred and seven hundred. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it; they left it because there is a difference in its text regarding the number. And Allah knows best.

It is narrated from Yazid bin Hayyan al-Taymi that he said: I was present with Sayyiduna Zayd bin Arqam (may Allah be pleased with him) when Ubaydullah bin Ziyad sent for him and said: What are these hadiths that have reached me about you, that you narrate from the Messenger of Allah (peace and blessings be upon him) and claim that he (peace and blessings be upon him) has a Pool in Paradise? He replied: The Messenger of Allah (peace and blessings be upon him) narrated this to us and promised it to us. He said: You are lying; you (Zayd bin Arqam) have grown old and senile. Zayd (may Allah be pleased with him) said: Indeed, these ears of mine heard it from the Messenger of Allah (peace and blessings be upon him), and I also heard him (peace and blessings be upon him) saying: "Whoever deliberately lies about me, let him take his seat in the Fire." And I have never lied about the Messenger of Allah (peace and blessings be upon him). It has a shahid (supporting narration) on the condition of Muslim, narrated from Zayd bin Arqam (may Allah be pleased with him), in which the Pool is mentioned in other words.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever separates from the Jama'ah (community) even by a handspan has thrown off the collar of Islam from his neck, until he returns (to the Jama'ah)." And he said: "Whoever dies while there is no Imam of the (Muslim) Jama'ah over him, his death is a death of Jahiliyyah (pre-Islamic ignorance)." And the Messenger of Allah (peace and blessings be upon him) delivered a sermon and said: "O people! I will be your forerunner at the Pool (the one who arrives first to receive you). Its extent is as the distance between Kufah and the Black Stone, and its vessels are as numerous as the stars. And I saw some people of my Ummah: when they came near me, a man appeared and took them away from me. Then another group came, and he did the same with them. So none of them succeeded (in reaching the Pool) except a few, like animals strayed from the herd (very few)." Sayyiduna Abu Bakr (may Allah be pleased with him) said: O Prophet of Allah! Am I among them? He (peace and blessings be upon him) said: "No, rather they are people who will come after you and will turn back on their heels (from the religion)." This hadith is sahih (authentic) according to the conditions of the two Shaykhs (Bukhari and Muslim), and Hajjaj bin Muhammad also narrated it from al-Layth, but they did not record it.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that he said: I went to Ubaydullah bin Ziyad while they (he and his companions) were arguing back and forth about the Pool of al-Kawthar. He said: Anas (may Allah be pleased with him) has come to you. Then he asked: O Anas! What do you say about the Pool? I said: I never imagined I would live long enough to see people like you doubting and arguing about the Pool. I have left behind me old women, not one of whom prays a prayer without asking her Lord to bring her to the Pool of Muhammad (peace and blessings be upon 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 Anas (may Allah be pleased with him) that he said: I went to Ubaydullah bin Ziyad while they were discussing the Pool; then he narrated the same as the previous narration. There is also a sahih shahid (supporting narration) of it from Humayd on the condition of the two Shaykhs (Bukhari and Muslim).

It is narrated from Sayyiduna Khabbab (may Allah be pleased with him) that he was sitting at the door of the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) came out while we were all sitting, and he said: "Listen to me." We said: O Messenger of Allah! We are listening. He (peace and blessings be upon him) said: "Indeed, after me there will be rulers; so do not affirm their lies and do not help them in their oppression, for whoever affirms their lies and helps them in their oppression will not be able to come to me at the Pool." This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs did not record it. Its shahid (supporting narration) is the well-known hadith that Imam al-Sha'bi narrated from Ka'b bin Ujrah, although there is a difference (among the narrators) about it.

It is narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) that one day the Messenger of Allah (peace and blessings be upon him) came out to us while we were in the mosque; five of us were Arabs and four were non-Arabs. He (peace and blessings be upon him) said: "Are you listening?" We said: Yes, we are listening. He (peace and blessings be upon him) asked twice, then said: "Listen! After me there will soon be rulers. Whoever goes to them, affirms their lies and helps them in their oppression, then he has nothing to do with me and I have nothing to do with him, and he will never come to me at the Pool. And whoever does not go to them, does not affirm their lies and does not help them in their oppression, he is from me and I am from him, and he will soon come to me at the Pool."

It is narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) that he narrated similar words, according to the narration of Sufyan (al-Thawri).
