The Prophet ﷺ said, "It is not fitting for any servant to say, 'I am better than Yunus bin Matta.'"
عن النبي ﷺ قال: ما ينبغي لعبد أن يقول: أنا خير من يونس بن متى.
Bukhari narrated it in the Hadiths of the Prophets (3413) and Muslim in the Book of Virtues (2377:166), both from the hadith of Shubah, from Qatada, who said, "I heard Abu Aliyah say, 'Ibn Abbas told me,'" and he mentioned it.
