It was narrated from Isma’eel bin Muhammad bin Sa"d bin Abi Waqqas, from his father, that his grandfather Sa"d bin Abi Waqqas said:

The Messenger of Allah (ﷺ) said: "One of the signs that the son of Adam is blessed is that he prays istikharah, asking Allah for guidance in making a decision. And of the signs that the son of Adam is blessed is his being content with what Allah decrees, And one of the signs that the son of Adam is wretched is that he does not pray istikharah, asking Allah for guidance in making a decision. And one of the signs that the son of Adam is wretched is his being discontent with what Allah decrees."
