The Messenger of Allah ﷺ said, "When one of you wakes up from sleep at night, he should not dip his hand into the vessel until he has washed it three times, for he does not know where his hand spent the night."
حدثنا أبو معاوية حدثنا الأعمش عن أبي صالح
قال رسول الله ﷺ إذا استيقظ أحدكم من الليل فلا يدخل يده في الإناء حتى يغسلها ثلاث مرات فإنه لا يدري أين باتت يده
Its chain is sahih, and it is a repetition of 7280, which has already appeared there through the narration of Sufyan from Zuhri, from Abu Salama, from Abu Hurairah. As for this route, it was narrated by Abu Dawud 103 [1:38 Awn al-Mabud], Muslim 1:92, Abu Awana in his Musnad [the one compiled on Sahih Muslim] 1:264, and Bayhaqi in Sunan al-Kubra 1:45, all of them through the route of Abu Muawiya, from Amash, with this chain. Except that their narration, apart from Abu Awana, is from Amash, from Abu Razeen and Abu Salih, from Abu Hurairah. Muslim did not mention its wording but referred back to another narration before it. Abu Awana did not mention the word "three times." The word "one of you" was not mentioned in H, and we added it from K and M. See the two narrations following this one.7432m, Waki said [...] from Abu Salih, Abu Razeen, from Abu Hurairah, raising it to the Prophet, "three times." Sahih.(7432m) Its chain is sahih, even though Imam Ahmad did not present it fully as a complete chain. This is because he only intended to point out Waki's narration, that it is marfu, and that it contains the word "three times," like the preceding narration of Abu Muawiya, and that it is not from Abu Salih alone but also from Abu Razeen, both of them from Abu Hurairah.It is not reasonable for the chain to be as it apparently appears here, Waki from Abu Salih and Abu Razeen, because Waki was born in the year 128, Abu Salih died in the year 101, and Abu Razeen died in the year 85. Rather, the hadith is Waki from Amash, from Abu Salih and Abu Razeen, both of them from Abu Hurairah. So Imam Ahmad omitted the mention of Amash from the chain, because he only intended to clarify the difference between the two narrations of Abu Muawiya and Waki, in that Waki mentioned Abu Razeen in the chain while Abu Muawiya did not mention him, though Abu Muawiya did also mention him in some of the narration from him, as we indicated before. He also intended to clarify their agreement on raising the hadith to the Prophet and on mentioning the number three.To remove this ambiguity in the chain, we added three dots between the two brackets of addition [...], as an indication of the omission in the chain. The same hadith will come again at 10093, with the complete chain, Waki, Amash narrated to us, from Abu Salih and Abu Razeen... Likewise it was narrated by Muslim 1:92, through the route of Waki, along with the narration of Abu Muawiya that comes before this one. Likewise it was narrated by Abu Awana 1:264 through the route of Waki. And it was narrated by Bayhaqi 1:45–46 through the route of Waki, from Amash, from Abu Razeen alone, from Abu Hurairah.This Abu Razeen, with fatha on the ra and kasra on the za, is Masud, the freed slave of Abu Waail al-Asadi, an early Tabii. We established in our commentary on hadith 3551, and in the correction numbered 707, that he is different from Abu Razeen Masud bin Malik, from whom Saeed bin Jubayr, his freed slave, narrates, both of them being narrated from by Amash. Bukhari distinguished between them in al-Kabir 4/1/423, under numbers 1855 and 1853. Likewise Ibn Abu Hatim distinguished between them, giving a biographical entry for the freed slave of Abu Waail in 4/1/22-283, under number 1695, and for the freed slave of Saeed bin Jubayr on page 284, under number 1300.
