Hadith on Qadr: Happiness in being pleased with Allah’s decrees

Sa’d reported: The Messenger of Allah, peace and blessings be upon him, said, “Among the happiness of the son of Adam is contentment with what Allah has decreed for him. Among the misery of the son of Adam is to abandon asking Allah for guidance, and among the misery of the son of Adam is displeasure with what Allah has decreed for him.
