‘Abd Al-Raḥmān b. ‘Awf – Allāh be pleased with him – was once brought some food, and he had been fasting. He said:

Muṣ’ab b. ‘Umayr was killed, and he was better than me and he was buried with a cloak as a shroud: if his head was covered with it his legs would be uncovered and if his legs were covered with it his head would be uncovered. And Ḥamzah was killed and he was better than me. Then, after that time, we were given what we were given of worldly wealth, and we fear that [the reward of] our good deeds has been quickened for us [in this life].

He then began to cry so much that he left his food.
