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)).
I came to Messenger of Allah (ﷺ) 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 (ﷺ) 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].
