Ibn Mas‘ūd (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) used to say: "O Allah, I ask You for guidance, piety, abstinence, and sufficiency."
This is one of the most comprehensive and useful invocations. It includes asking for religious and worldly benefits. 'Guidance' means beneficial knowledge; 'piety' means righteous deeds and avoiding divine and prophetic prohibitions; 'abstinence' means not harming people, and avoiding immoralities; 'sufficiency' means being satisfied with Allah and with divine provisions, and developing content in the heart.
