Displaying Humility towards the Traveler
Tamim bin Usaid (radi Allahu anhu) reported: I came to Messenger of Allah (sal Allahu alaihi wa sallam) 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.” The Messenger of Allah (sal Allahu alaihi wa sallam) 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.
Allah says (interpretation of the meaning): “And be kind and humble to the believers who follow you.” [ash-Shu'ara 26:215]
This above Hadith also mirrors, apart from the extreme humbleness of the Prophet (sal Allahu alaihi wa sallam), his affability and consolation for a traveler as well as the priority which he gave to faith and Islamic teachings.
This Hadith also teaches us that during the delivery of sermon, if it is needed, the preacher can converse with somebody and also leave the pulpit temporarily.
And Allah knows best!
