Abu Najeeh reported,
We were besieging, alongside the Messenger of Allah ﷺ, the fortress of Taif. Muaz said, "I heard Ubayy say, 'at the fortress of Taif, at the stronghold of Taif,' all of this."I heard the Messenger of Allah ﷺ say, "Whoever shoots an arrow in the cause of Allah 
will earn a rank in Paradise."He continued the hadith.I also heard the Messenger of Allah ﷺ say, "Any Muslim man who frees a Muslim man, Allah will make every bone of the freed man a shield for every bone of his own against the Fire. And any woman who frees a Muslim woman, Allah will make every bone of the freed woman a shield for every bone of her own against the Fire on the Day of Resurrection."

Sahihعن أبي نجيح السلمي هو عمرو بن عبسة قال
حاصرنا مع رسول الله ﷺ بقصر الطائف-قال معاذ: سمعت أبي يقول: بقصر الطائف، بحصن الطائف كل ذلك- فسمعت رسول الله ﷺ يقول: من بلغ بسهم في سبيل الله عز وجل فله درجة. وساق الحديث. وسمعت رسول الله ﷺ يقول: أيما رجل مسلم أعتق رجلا مسلما فإن الله عز وجل جاعل وقاء كل عظم من عظامه عظما من عظام محرره من النار. وأيما امرأة أعتقت امرأة مسلمة فإن الله جاعل وقاء كل عظم من عظامها عظما من عظام محررها من النار يوم القيامة.
Abu Dawud (3965), Tirmidhi (1638), and Nasai (3143) narrated it, and Ibn Hibban (4615), Hakim (2/95, 3/49-50), Bayhaqi (10/272), and Ahmad (17022) graded it sahih, all of them through various paths from Hisham bin Abu Abdullah, from Qatada, from Salim bin Abu Jaad, from Madan bin Abu Talha, from Abu Najeeh Sulami, who said, and then he related it, though some of them abridged it. Tirmidhi said, "This is a sahih hadith. Abu Najeeh is Amr bin Abasa." Hakim said, "Sahih according to the criterion of the two Shaykhs (Bukhari and Muslim)."I say, Salim bin Abu Jaad narrates this hadith from Madan bin Abu Talha, just as he also narrates it from a man, from Abu Najeeh, so it appears that the unnamed man is Madan bin Abu Talha. He also narrates it from Kaab bin Mura, but Shuba inserted Shurahbil bin Simt between them. This was narrated by Abu Dawud (3967) and Tahawi in his Mushkil (726). Abu Dawud said, "Salim bin Abu Jaad did not hear from Shurahbil bin Simt." Likewise, Ibn Majah (2522) narrated it through the path of Amash, from Amr bin Mura, from Salim bin Abu Jaad. Salim bin Abu Jaad has been described as practicing tadlis and frequently narrating with mursal transmission.
