Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "There were Muhaddithun (the recipients of Divine inspiration) among the nations before you. If there is any of such Muhaddith among my followers, he must be 'Umar."

[Al-Bukhari].

In Muslim, this Hadith is narrated by 'Aishah (May Allah be pleased with her), and in both these narrations Ibn Wahb has said that the meaning of Muhaddithun is recipients of Divine inspiration.

وعن أبي هريرة رضي الله عنه قال: قال رسول الله ﷺ: "لقد كان فيما قبلكم من الأمم ناس محدثون، فإن يك في أمتي أحد، فإنه عمر" ((رواه البخاري، ورواه مسلم من رواية عائشة، وفي روايتهما قال ابن وهب: "محدثون" أي: ملهمون)).
