They asked, "Messenger of Allah, which struggle is the most excellent?"He replied, "That of one whose horse is hamstrung and whose blood is shed."
قالوا: يا رسول الله، أي الجهاد أفضل؟ قال: من عقر جواده، وأهريق دمه.
Ahmad (4210) and Darimi (2437) narrated it, and Ibn Hibban (4639) graded it sahih, all of them by way of Amash, from Abu Sufyan, from Jabir, who related it as mentioned. This is a sahih chain of transmission.It has also been narrated from the hadith of Abu Musa, but this is a mistake. Bazzar said, following the narration of Abu Musa, "We do not know of anyone who narrated this hadith from Amash, from Shaqiq, from Abu Musa, except Abdul-Malik bin Abu Ghaniya. Apart from Ibn Abu Ghaniya, it is only narrated from Amash, from Abu Sufyan, from Jabir, from the Prophet ﷺ." Musnad Bazzar (3016).I say, it is just as he said.
