The Prophet ﷺ said, "The martyr is granted six privileges at the first drop of his blood. Every sin of his is forgiven, he is shown his place in Paradise, he is married to the wide-eyed houris, he is secured from the Great Terror and from the punishment of the grave, and he is adorned with the garment of faith."
قال النبي ﷺ: يعطى الشهيد ست خصال عند أول قطرة من دمه: يكفر عنه كل خطيئة، ويرى مقعده من الجنة، ويزوج من الحور العين، ويؤمن من الفزع الأكبر، ومن عذاب القبر، ويحلى حلة الإيمان.
Imam Ahmad narrated it (17783) from Zayd bin Yahya Dimashqi, who said, "Ibn Thawban narrated to us, from his father, from Makhul, from Kathir bin Mura, from Qays Juzami," and he mentioned it. The men of its chain are trustworthy except for Ibn Thawban, who is Abdul-Rahman bin Thabit bin Thawban Shami. Ibn Main's statement about him varied, for he once said, "He is daif, but his father is trustworthy," and another time said, "There is no harm in him." He also said, "Ibn Thawban originally came from Khurasan and settled in Syria, and they only spoke well of him." Ibn Adi gave his biography in Kamil (4/1591 - 1993) and said, "I have written down his hadith from Ibn Jawsa and Abu Aruba, from both of them, and his hadiths that reach us are sound, and he was a righteous man, and his hadith is recorded despite his weakness."However, Sufyan differed from him, narrating it from Barad bin Sinan, from Makhul, and stopping it at him as his own statement rather than tracing it to the Prophet. Ibn Abu Shayba narrated this (5/307) from Waki, from Sufyan. Barad bin Sinan is Abu Ala Dimashqi, whom Ibn Main and others considered trustworthy, while Ali bin Madini considered him daif. Even giving preference to the view that it stops at the companion, it still carries the ruling of being traced back to the Prophet, for affirming punishment, reward, and prohibition cannot be a matter of personal opinion.Meanwhile, Abu Naeem narrated it in Marifat Sahaba (5723) through another route, from Abu Tuba Rabi bin Nafi, who said, "Haytham bin Humayd narrated to us, from Zayd bin Waqid, from Kathir bin Mura," with the same content, traced back to the Prophet, and it contains the words, "and he is granted refuge from the punishment of the grave." Haytham bin Humayd is Ghassani, whom Ibn Main and Abu Dawud considered trustworthy, while Nasai said, "There is no harm in him." This is a strong corroboration of the hadith of Abdul-Rahman bin Thabit bin Thawban.Qays Juzami is Ibn Zayd bin Jabbar, and in Isaba he is called Ibn Jabbar Juzami. The majority of scholars affirmed that he was a companion, except Ibn Abu Hatim, who denied this. The correct view is what the majority held. Al-Hafiz mentioned in Isaba the story of his delegation to the Prophet ﷺ and the Prophet's supplication for him.
