About two weeks after the Prophet ﷺ returned to Madinah from the Conquest of Makkah, Ka'b ibn Zuhayr, the most renowned poet in the Arabian Peninsula, who had written vulgar satirical poetry against the Muslims, came secretly to Madinah to seek forgiveness. He entered unrecognized by face, stayed the night at the house of a relative, and after Fajr approached the Prophet ﷺ in disguise, put his hand in the Prophet ﷺ's hand, and asked whether protection would be granted to Ka'b ibn Zuhayr if he repented. When the Prophet ﷺ agreed, Ka'b revealed himself. An Ansari rose to strike him down, but the Prophet ﷺ stopped him. Ka'b then recited his praise-poem for the Prophet ﷺ, known as the Qasidat al-Burda (Banat Su'ad), the original poem of this name, distinct from the later, more famous Qasidat al-Burda of al-Busiri (a 7th-century-Hijrah poet who claimed to have seen the Prophet ﷺ in a dream).
The entire tribe of Muzayna, roughly 400 people, came to Madinah in the Year of Delegations to embrace Islam. When they prepared to return home, the Prophet ﷺ instructed Umar ibn al-Khattab RA to provide them food for the journey. Umar had only one bag of dates at home, but obeyed anyway, and found his room filled with dates to the ceiling. All 400 delegates filled their sacks from it, and the pile was reported unchanged when the last of them left.
