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

[Al-Bukhari].

وعن أبي هريرة رضي الله عنه ، أن رجلاً قال للنبي ﷺ: أوصني، قال: "لا تغضب" فردد مراراً، قال: " لاتغضب" رواه البخاري.
