Hadith: I came to the Messenger of Allah (may Allah's peace and blessings be upon him) while he was giving a sermon

عن أبي رِفَاعَةَ تَمِيم بن أُسَيدٍ رضي الله عنه قَالَ: انتهيتُ إلى رسولِ اللهِ صلى الله عليه وسلم وهو يَخطبُ، فَقُلتُ: يَا رسولَ اللهِ، رَجُلٌ غَريبٌ جاءَ يَسألُ عن دِينِهِ لا يَدرِي مَا دِينُهُ؟ فَأَقْبلَ عليَّ رسولُ اللهِ صلى الله عليه وسلم وتَرَكَ خُطبتَهُ حتى انتَهى إليَّ، فأُتِيَ بكُرسِيٍّ، فَقَعَدَ عليه، وجَعَلَ يُعَلِّمُنِي ممّا عَلَّمَهُ اللهُ، ثم أتى خُطبتَهُ فَأَتَمَّ آخِرَهَا.
[صحيح] - [رواه مسلم بزيادة: بكرسي حسبت قوائمه حديداً]

Abu Rifā‘ah Tamīm ibn Usayd (may Allah be pleased with him) reported: I came to the Messenger of Allah (may Allah’s peace and blessings be upon him) while he was giving a sermon, and I said: "O Messenger of Allah, a stranger (meaning himself) has come to inquire about his religion. He is quite ignorant about his religion." So the Messenger of Allah (may Allah’s peace and blessings be upon him) interrupted his sermon and came to me. A chair was brought for him and he sat on it and started teaching me of what Allah has taught him. Then he resumed his sermon and completed it.
[Authentic hadith] - [Narrated by Muslim]

Explanation

An aspect of the humility of the Prophet (may Allah's peace and blessings be upon him) is shown when a man came to him while he was delivering a sermon and told him that he was a stranger who wished to learn about the religion. The Prophet gave him attention; he stopped his sermon and walked toward him. Then he was brought a chair to sit on, and he started teaching the man, because this man came with a desire to learn his religion in order to act upon it. After teaching him, the Prophet (may Allah's peace and blessings be upon him) continued his sermon.
