Musannaf Ibn Abi Shayba 28:287

Shababa narrated to us, he said: Layth ibn Sa’d informed me, from Ibn Shihab, from ‘Abd al-Rahman ibn Malik, that Jabir ibn ‘Abd Allah informed him that the Prophet, peace and blessings of Allah be upon him, did not perform the funeral prayer over the martyrs of Uhud, and they were not washed.
