Ishaq bin Mansur al-Kausaj إسحاق بن منصور بن بهرام - الكوسج · The Book on Jihad

A man came to Prophet (ﷺ) seeking permission to go for Jihad. So he said: 'Do you have parents (living)? ' He said: 'Yes.' He said: 'Then it is for them that you should perform Jihad.'" There is something on this topic from Ibn 'Abbas. This Hadith is Hasan Sahih. (One of the narrators) Abul-Abbas is the blind (Al-A'ma) poet (Ash-Sha'ir), from Makkah, and his name is As-Sa'ab bin Farrukh.

That Ibn Sirin said: "I made my sword like the sword of Samurah bin Jundab. Samurah claimed that he made his sword like the sword of the Messenger of Allah (ﷺ), and it was a Hanafiyah." This Hadith is Gharib, we do not know of it except through this route. Yahya bin Sa'eed Al-Qattan has criticized 'Uthman bin Sa'd the scribe, and he graded him weak due to his memory.

] This Hadith is Hasan Gharib Sahih.
