Riyad as-Salihin, Book 1, Hadith 607 (In-Book) ⓘ

Tamim bin Usaid (May Allah be pleased with him) reported: I came to Messenger of Allah while he was delivering a Khutbah and said: "O Messenger of Allah, a stranger (meaning himself) has come to inquire about his Deen. He is quite ignorant about his Deen." Messenger of Allah interrupted his Khutbah and turned to me. Then a chair was brought for him and he sat on it. He started instructing me what Allah had taught him. Then he resumed his Khutbah and completed it.[Muslim].

وعن أبي رفاعة تميم بن أسيد رضي الله عنه قال‏:‏ انتهيت إلى رسول الله صلى الله عليه وسلم وهو يخطب، فقلت‏:‏ يا رسول الله رجل غريب جاء يسأل عن دينه لا يدرى ما دينه‏؟‏ فأقبل علي رسول الله صلى الله عليه وسلم، وترك خطبته حتى انتهى إلى فأتى بكرسي، فقعد عليه وجعل يعلمني مما علمه الله ثم أتى خطبته فأتم آخرها”‏.‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
