Awn narrates: When the news of the death of his brother Utbah reached Abdullah bin Mas'ud (may Allah be pleased with him), he wept. It was said to him: "You weep?" He said: "He was my brother by lineage, and my companion with the Messenger of Allah (peace and blessings be upon him), and despite that I would not have liked to die before him. That he should die and I hope for reward through patience over him is dearer to me than that I should die and he should be patient over my death and attain reward."
