Abu Umamah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "O son of Adam, if you spend the surplus, it will be better for you; and if you retain it, it will be evil for you. You will not be reprimanded for storing what is enough for your need. First of all spend upon those who are your dependents."[At- Tirmidhi, who classified it as Hadith Hasan Sahih].
