A man from the tribe of Banu Kinanah called al-Mukhdaji heard a man in Syria known as Abu Muhammad saying that the witr prayer is obligatory. Al-Mukhdaji said, "I went to Ubada bin Samit and intercepted him as he was on his way to the mosque, and I told him what Abu Muhammad had said."Ubada replied, "Abu Muhammad is wrong. I heard the Messenger of Allah ﷺ say, 'Five prayers has Allah, the Mighty and Majestic, prescribed upon His servants. Whoever performs them without neglecting any of them out of disregard for their right will have a covenant with Allah that He will admit him into Paradise. And whoever does not perform them has no covenant with Allah. If He wills, He will punish him, and if He wills, He will admit him into Paradise.'"
أن رجلا من بني كنانة يدعى المخدجي رجلا بالشام يكنى أبا محمد يقول: إن الوتر واجب. فقال سمع المخدجي: فرحت إلى عبادة بن الصامت، فاعترضت له وهو رائح إلى المسجد. فأخبرته بالذي قال أبو محمد، فقال عبادة: كذب أبو محمد، سمعت رسول الله ﷺ يقول: خمس صلوات كتبهن الله عزوجل على العباد، فمن جاء بهن لم يضيع منهن شيئا استخفافا بحقهن كان له عند الله عهد أن يدخله الجنة. ومن لم يأت بهن فليس له عند الله عهد. إن شاء عذبه، وإن شاء أدخله الجنة.
Malik related it in the chapter on Night Prayer (14) from Yahya bin Saeed, from Muhammad bin Yahya bin Habban, from Ibn Muhayriz, and mentioned it. Abu Dawud (1420) and Nasai (461) both related it through Malik with the same wording. Ibn Majah (1401) related it through Muhammad bin Yahya bin Habban with the same wording.Munziri said, "Abu Umar Namri said, 'There is no disagreement regarding Malik's chain for this hadith, and it is a sahih, established hadith.'" Ibn Hibban graded it sahih (1732) and related it through Yahya bin Saeed with the same wording, except that he said, "A man came to Ubada bin Samit," without naming him. He also related it through other chains from Muhammad bin Yahya bin Habban with the same wording, naming the man as Mukhdaji, who is Abu Rafi (1731, 2471).Abu Muhammad was a man from the Ansar who was a companion. His statement "he lied" means "he erred," not that he deliberately lied in the sense that is the opposite of truthfulness, for lying only applies to reports, whereas this Abu Muhammad had merely given a legal opinion, forming a view in which he erred in what he pronounced. This is what Khattabi explained.Mukhdaji is Abu Rafi, and it is also said Rafi. Abdullah bin Muhayriz was the only one who narrated from him, and no authentication of him has been transmitted from anyone other than Ibn Hibban. Malik's narrating from him is considered, by some scholars, a form of authentication, since he would only narrate from trustworthy narrators. However, he was not alone in narrating it, for Abdullah Sanabihi corroborated him, and its sourcing was mentioned earlier at the beginning of the Book of Prayer, in the chapter on emphasizing the prayers and maintaining them.Abu Idris Khawlani also corroborated him, as found in Abu Dawud Tayalisi (574), who related it from Zama, from Zuhri, from Abu Idris Khawlani, who said, "I was in a gathering of the companions of the Prophet ﷺ, among whom was Ubada bin Samit, and they spoke of Witr." Some of them said, "It is obligatory," and some said, "It is sunnah." Then Ubada bin Samit spoke, and he mentioned something similar, except that it included, "Jibreel said, 'O Muhammad, Allah says, "I have made five prayers obligatory upon your nation,"'" and so on.Thus he made the report into a divine hadith, one whose wording is attributed directly to Allah's own speech. Zama is Ibn Salih Jundi, who is daif, and his narration in Muslim only occurs paired with another narrator. Perhaps this alteration was his own doing, attributing the obligation of the five prayers to Allah according to the established original wording, even though in the hadith of Ubada bin Samit it is not a divine hadith.
