The Messenger of Allah ﷺ said, "Hold fast to praying at night, for it was the practice of the righteous before you. It draws you near to your Lord, wipes away your bad deeds, and keeps you from sin."
قال رسول الله ﷺ: عليكم بقيام الليل، فإنه دأب الصالحين قبلكم، وهو قربة إلى ربكم، ومكفرة للسيئات، ومنهاة عن الإثم.
Ibn Khuzayma (1135) narrated it, as did Hakim (1/308), and from him Bayhaqi (2/502), all of them through the route of Abdullah bin Salih, who said, Muawiya bin Salih narrated to me, from Nur bin Yazid, from Abu Idris Khawlani, from Abu Umama Bahili, and he mentioned it. Except that Ibn Khuzayma said, "Rabia bin Yazid." Hakim said, "Sahih according to the criterion of Bukhari." This is a mistake on his part, for Muawiya bin Salih, who is the son of Hudayr, was not narrated from by Bukhari at all, only by Muslim, and he is "truthful but has misgivings" as stated in Taqrib, where he is marked with the symbol (M). However, in the chain is Abdullah bin Salih, the scribe of Layth, and although Bukhari cited him in the muallaqat (suspended reports), he is a disputed figure. Nasai said, "He is not reliable." Hakim said, "His hadith is to be discarded." Ibn Adi examined his hadiths and said, "In my view his hadith is generally sound, except that errors occur in his chains and texts, though he does not deliberately lie."I say, here he has not brought anything objectionable, so there is no objection to citing him in corroboration, though not as independent evidence.As for what Tirmidhi (3549) narrated through the route of Bakr bin Khunays, from Muhammad Qurashi, from Rabia bin Yazid, from Abu Idris Khawlani, from Bilal bin Rabah, from the Messenger of Allah ﷺ with similar wording, adding at the end, "and it drives away disease from the body," this does not undermine what Abdullah bin Salih narrated from Muawiya bin Salih through this route.Tirmidhi said, "A rare hadith, we do not know it from the hadith of Bilal except through this route, and it is not sound as regards its chain. I heard Muhammad bin Ismail say, Muhammad Qurashi is Muhammad bin Saeed Shami, who is Muhammad bin Abu Qays, who is Muhammad bin Hassan, and his hadith has been abandoned. This hadith was narrated by Muawiya bin Salih, from Rabia bin Yazid, from Abu Idris Khawlani, from Abu Umama, from the Messenger of Allah ﷺ, and this is more sahih than the hadith of Abu Idris from Bilal."I say, it is as he said, for this Shami is the one who was crucified, whom they declared a liar, and Mansur had him executed for heresy and crucified him. As for his teacher Rabia bin Yazid, he is reliable and devout as stated in Taqrib. The first chain contains no one suspect, and it is hasan, Allah willing.There is also on this subject a report from Salman Farsi, worded as follows, "You must engage in night prayer, for it was the habit of righteous people before you, a means of drawing you close to Allah , an expiation for sins, a deterrent from wrongdoing, and it drives away disease from the body." However, it is daif due to the obscurity of one of its narrators. Tabarani narrated it in Kabir (6154), and in it is Abdul-Rahman bin Sulayman bin Abu Jawn, whom Duhaym, Ibn Hibban, and Ibn Adi considered reliable, while Abu Dawud and Abu Hatim considered him weak. This is what Haythami said in Majma (3520).Ibn Adi mentioned him in Kamil (4/1596-1597) and cited several hadiths of his, including the one mentioned, and said, "This Ibn Abu Jawn is like Ibn Abu Rijal, most of his hadiths are sound, though some contain a degree of objection, and that is why I mentioned him. He has hadiths beyond what I have cited, and Walid bin Muslim and his peers among the people of Damascus narrated from him, and I hope there is no harm in him." End of quote. As for Abu Dawud, he considered him weak as mentioned earlier, and Abu Hatim said, "His hadith is recorded but not relied upon as proof." Also in it is Abu Ala Ghazzi, the narrator from Salman Farsi, who is unknown. Dhahabi said, "I do not know him."There is also on this subject what was reported from Abdullah bin Ibn Abbas, who said, "Night prayer was mentioned, and some of them said that the Messenger of Allah ﷺ said, 'Half of it, a third of it, a quarter of it, the time it takes to rest between two milkings of a she-camel, the time it takes to rest between two milkings of a ewe.'" Abu Yaala narrated it in Maqsad Ali (396), from Harun bin Maruf, who said Ibn Wahb narrated to us, Makhrama bin Bukayr narrated to me, from his father, from Ibn Abbas, and he mentioned it. Makhrama bin Bukayr's hadith is hasan.Haythami said in Majma (2/252), "Abu Yaala narrated it, and its narrators are the narrators of the Sahih." Busiri said in Ithaf Khayra (2353), "Abu Yaala narrated it with a sahih chain." I say, it is indeed so, except that Makhrama bin Bukayr, one of Muslim's narrators, transmitted from his father through wijada, that is, by finding it written in his father's book, as Ahmad and Ibn Main stated. Ibn Madini said, "He heard little from his father directly," and wijada is accepted among the scholars of hadith. However, its defect is that there is a disconnection in it, for Bukayr, who is the son of Abdullah bin Ashaj, did not hear directly from Ibn Abbas.As for his statement, "the time it takes to rest between two milkings of a she-camel," it means the amount of rest between two milkings. This is from Nihaya by Ibn Athir.As for what was reported from Abu Hurairah as a saying of the Prophet, "The nobility of the believer is his prayer at night, and his dignity is his independence from other people," this is daif. Aqeeli narrated it in Duafa (2/37), from Yahya bin Uthman bin Salih, who said, Dawud bin Uthman Thaghri narrated to us, who said, Abdul-Rahman bin Amr Uzai narrated to us, from Abu Muaz, from Abu Hurairah, and he mentioned it. Aqeeli said, "Dawud bin Uthman Thaghri used to relate baseless reports in Egypt from Uzai and others, among them the hadith of Yahya bin Uthman," and he mentioned it. He also said, "This is related from Hasan and others as their own statement, and it has no traceable basis as a hadith."Ibn Jawzi cited it in Mawdhuat (2/407) through the route of Aqeeli, and confirmed his prior statement, and cited a corroborating report, the hadith of Sahl bin Saad, as a saying of the Prophet, "Jibreel came to the Prophet ﷺ and said, 'O Muhammad, love whom you wish, for you will part from him, do as you wish, for you will be repaid for it, live as long as you wish, for you will die, and know that the nobility of the believer is his standing in prayer at night, and his dignity is his independence from other people.'" He said, "This is not sound as coming from the Prophet ﷺ, for in its chain is Muhammad bin Humayd, whom Abu Zura and Ibn Wara declared a liar, and Ibn Hibban said, 'He alone transmits inverted reports that the reliable narrators do not.' Also in it is his teacher Zafir bin Sulayman, of whom Ibn Adi said, 'He is not corroborated in most of what he narrates.'" End of quote.
