The Messenger of Allah ﷺ said, "Whoever claims descent from someone other than his true father will not smell the fragrance of Paradise, even though its fragrance can be perceived from a distance of seventy years, or a journey of seventy years. And whoever lies about me deliberately, let him take his seat in the Fire."
حدثنا وهب يعني ابن جرير حدثنا شعبة عن الحكم عن مجاهد قال أراد فلان أن يدعى جنادة بن أبي أمية فقال
رسول الله ﷺ من ادعى إلى غير أبيه لم يرح رائحة الجنة وإن ريحها ليوجد من قدر سبعين عاما أو مسيرة سبعين عاما قال ومن كذب علي متعمدا فليتبوأ مقعده من النار
Its chain of transmission is sahih. Wahb is the son of Jareer bin Hazim, whose reliability was established earlier at 725, and we add here that Sulayman bin Dawud Bazzar said to Ahmad, "I want to go to Basra, from whom should I write?" He said, "From Wahb bin Jareer and Abu Amir Aqadi." Ibn Saad recorded this in al-Tabaqat 7/2/51, and in al-Tahdheeb 11:162 there is a statement attributed to Ahmad that we do not believe is authentically from him, saying that Ahmad said, "Wahb never narrated from Shuba at all, but Wahb was a man devoted to the sunnah." This denial is contradicted by the established fact of Wahb's narration from Shuba in the Musnad, this passage being one instance of it. Moreover, Bukhari, in al-Kabir 4/1/169, gave his biography and confirmed that he heard from him, saying, "He heard from Shuba and from his father."Hakam is the son of Utayba, with a damma on the ayn, a fatha on the ta, and the ba, with a silent ya between them. He is a reliable, firmly established, well-known narrator. Ibn Saad said in 6:231, "Hakam bin Utayba was reliable, a jurist, learned, of high standing, and had many hadiths." Bukhari also gave his biography in al-Kabir 1/2/330-331.This hadith was narrated by Khatib in Tarikh Baghdad 2:347, through the route of Muhammad bin Abdul-Malik Daqiqi, from Wahb bin Jareer, with this same chain, but in abridged form, restricting it to only the part attributed directly to the Prophet regarding one who claims descent from someone other than his real father. He did not mention the story at the beginning, nor the warning against lying at the end. The name of the companion appears there as Abdullah bin Umar, which is an error by a copyist or a printer. This hadith will also come again in abridged form at 2834, through the narration of Muhammad bin Jafar from Shuba.Ibn Majah also narrated it, 2:68, through the route of Sufyan, from Abdul-Kareem, from Mujahid, attributed directly to the Prophet and also in abridged form, but it contains the addition, "and its scent can be detected from a distance of five hundred years." Busiri said in his Zawaid, "Its chain of transmission is sahih." Haythami also mentioned it in Majma al-Zawaid 1:98, likewise in abridged form, and said, "Ahmad narrated it, and its narrators are the narrators of the sahih collections," pointing to the narration of Ibn Majah that we have mentioned. See also what has already passed at 5998, and what will come at 7019.Regarding Junada bin Abu Umaya, there are three separate biographical entries for this name among the scholars. The correct view, favored by Ibn Abdul-Barr and Ibn Hajar, is that they are actually two people, Junada bin Abu Umaya Azdi, a companion, who will have one hadith attributed to him in the Musnad at 16671, and the other being Junada bin Malik Azdi, a successor. We may, Allah willing, succeed in resolving this dispute when we reach that hadith. See also al-Kabir by Bukhari 1/2/231-232, Ibn Saad 7/2/151, 194, al-Istiab 94-95 (three entries), Usd al-Ghaba 1:297-298, 299-300 (also three entries), al-Isaba 1:256-257, 258, 275 (also three entries), and al-Tahdheeb 2:115-116.As for "the scent of Paradise," Ibn Athir said, "That is, he did not smell its fragrance. It is said raha yarihu, and raha yarahu, and araha yarihu, when one detects the scent of something."
