The number of those present at Badr was the same as the number of the companions of Talut on the day they faced Jalut, three hundred and seventeen.
كان عدة أهل بدر عدة أصحاب طالوت يوم جالوت: ثلاثمائة، وسبعة عشر.

Bazzar narrated it in Kashf Astar (1784) from Amr bin Ali, who said, "Ibn Abu Adi narrated to us, Thabit bin Umara narrated to us, from Ghunaym bin Qays, from Abu Musa," and he related it. Bazzar said, "We do not know it from Abu Musa except through this route." Its isnad is hasan because of Thabit bin Umara, for there is disagreement about him, though his hadith is hasan. Haythami said in Majma (6/93), "Its narrators are trustworthy."In the same vein is what was narrated from Ibn Abbas, who said, "The people of Badr numbered three hundred and thirteen men, of whom the emigrants were seventy-six. The rout of the people of Badr took place on a Friday, when seventeen days of Ramadan had passed." Ahmad (2232) and Bazzar in Kashf Astar (1783) both narrated it, through two routes, from Hajjaj, from Hakam, from Miqsam, from Ibn Abbas, who related it. Bazzar added, "The banner of the emigrants was with Ali bin Abu Talib, and the banner of the Ansar was with Saad bin Ubada."The narrator from Hajjaj is Nasr bin Bab, the teacher of Imam Ahmad. The majority of scholars held him to be daif, though Imam Ahmad had a favorable opinion of him and said, "There was nothing wrong with him. They only objected to him when he narrated from Ibrahim Sayigh." He was also corroborated in Bazzar's narration. But it contains Hajjaj, who is Ibn Artaa, a mudallis, and he narrated it using "an" (without clearly stating direct transmission).Bukhari mentioned the names of those who were named among the people of Badr in his Sahih, in alphabetical order, as follows.1. The Prophet Muhammad bin Abdullah, the Hashimite. ﷺ His noble name was placed first because of his standing.

25. Ubayda bin Harith, the Qurashi.
26. Ubada bin Samit, the Ansari.

32. Asim bin Thabit, the Ansari.
33. Uwaym bin Saada, the Ansari.
34. Itban bin Malik, the Ansari.
35. Qudama bin Mazun.
36. Qatada bin Numan, the Ansari.
37. Muaz bin Amr bin Jamuh.
38. Muawwiz bin Afra.
39. And his brother.
40. Malik bin Rabia, Abu Usayd, the Ansari.
41. Murara bin Rabi, the Ansari.
42. Maen bin Adi, the Ansari.
43. Mistah bin Athatha bin Abbad bin Muttalib bin Abd Manaf.
44. Miqdad bin Amr, the Kindi, an ally of Banu Zahra.
45. Hilal bin Umaya, the Ansari. See Sahih Bukhari, Book of Military Expeditions, Chapter on the Naming of Those Named Among the People of Badr.As for Uthman bin Affan, Bukhari also mentioned him in the index, then said, "The Prophet ﷺ left him behind with his daughter, and allotted him a share of the spoils." Likewise, Bukhari mentioned in the Book of Military Expeditions (4007) Abu Masud Uqba bin Amr, the Ansari, among those who witnessed Badr, but did not mention him in the index, and this is correct, for he did not witness Badr, but rather settled there and so came to be named after it. See Isaba (5631) and Fath (7/319).Likewise, what Abu Dawud (2731) narrated from Saeed bin Mansur, which is also found in his Sunan (2466), is not sound, "Abu Muawiya narrated to us, from Amash, from Abu Sufyan, from Jabir, who said, 'I used to draw water for my companions on the day of Badr.'" Its narrators are trustworthy, but it is shadh, because the correct view is that Jabir did not witness Badr, as he himself stated with Muslim (1813). He only witnessed the pledge of Aqaba with his father and his maternal uncle, as Daraqutni and others said. His word "amih" comes from al-maih, the one who goes down to the bottom of the well, fills the bucket, and raises it up to the maih, who is the one who pulls up the bucket.Bukhari, may Allah have mercy on him, mentioned only forty-four men among the people of Badr, because these were the ones mentioned with a full chain of transmission in various places in his book Jami Sahih, and that is why he titled the chapter, "The Naming of Those Named Among the People of Badr in the Jami."As for their actual number, it reaches three hundred and thirteen without doubt, and reaches three hundred and fifty when accounting for the disagreement among reports. The reason for that goes back to the disagreement over some of the names, as Ibn Hajar said in Fath (7/329), and he mentioned that Hafiz Dia Din covered them comprehensively in the book Ahkam.
