One morning, the morning of the battle of Uhud, a group of people drank wine, and they were all killed that very day as martyrs. This was before wine was forbidden.
صبح أناس غداة أحد الخمر، فقتلوا من يومهم جميعا شهداء، وذلك قبل تحريمها.
Bukhari narrated it in his tafsir (4618) from Sadaqa bin Fadl, Ibn Uyayna informed us, from Amr, from Jabir, and he mentioned it. Bazzar narrated it in his Musnad from Ahmad bin Abdah, Sufyan narrated to us, from Amr bin Dinar, who heard Jabir bin Abdullah say, "Some people among the companions of the Prophet ﷺ drank wine in the morning, then were killed as martyrs on the day of Uhud. The Jews said, 'Some of those who were killed died with it still in their bellies.' So Allah revealed, "There is no blame upon those who believe and do righteous deeds for what they have eaten"." Bazzar said, "This isnad is sahih." Ibn Kathir said, "But there is strangeness in its wording." I say, this is because the prohibition of wine came after Uhud.It is also narrated from Bara, who said, "A man among the companions of the Prophet ﷺ died before wine was prohibited. When wine was prohibited, some men said, 'What about our companions who died while drinking wine?' So it was revealed, "There is no blame upon those who believe and do righteous deeds" [Maidah 5:93]." Tirmidhi narrated it (3050) through the route of Israil, and in (3051) through the route of Shuba, both of them from Abu Ishaq, from Bara, and he mentioned it. He graded it sahih from both routes. Ibn Jareer likewise reported it (8/667), as did Ibn Abu Hatim (4/1201), and Ibn Hibban graded it sahih (5350, 5351), all of them through the route of Shuba, with the same wording.However, Abu Yaala narrated it (1719, 1720) with two sahih isnads from Shuba, adding at the end, Shuba said, "I asked, 'Did you hear it from Bara?' He said, 'No.'" This makes clear that there is an intermediary between Abu Ishaq and Bara who is not known. This shows that Abu Ishaq practiced tadlis in this chain, and this is the damaging kind of tadlis.
