Musnad Ahmad 30:2393

Isma'il narrated to us, Ibn 'Awn narrated to us, from Hilal ibn Abi Zaynab, from Shahr ibn Hawshab, from Abu Hurayrah, who said: The martyr was mentioned in the presence of the Prophet, may Allah bless him and grant him peace, and he said: "The earth does not dry from his blood until his two wives hasten to him, as if they were two she-camels that had lost their young in a wide expanse of land. In the hand—or he said: in the hands—of each one of them is a garment that is better than the world and what is in it."
