Abu Hurairah (May Allah be pleased with him) reported:
A man asked the Prophet ﷺ to give him advice, and he ﷺ said, "Do not get angry." The man repeated that several times and he ﷺ replied (every time), "Do not get angry."

[Al-Bukhari].

وعن أبى هريرة رضي الله عنه أن رجلاً قال للنبى ﷺ: أوصنى قال: “لا تغضب” فردد مراراً، قال: “لا تغضب”. ((رواه البخارى)).
