Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) was on a journey when he received news of his son's death. So he stopped, performed two units of prayer, then recited: "Indeed we belong to Allah, and indeed to Him we shall return," and said: "We have done what Allah Almighty has commanded us: 'And seek help through patience and prayer.'"
