When Abu Huraira accompanied by his slave came intending to embrace Islam, they lost each other on the way. (When the slave showed up) Abu Huraira said (to the Prophet), "I make you witness that the slave is free for Allah's Cause."
Sahih al-Bukhari Book 49, Hadith 16
← Previous Hadith On my way to the Prophet (ﷺ) I was reciting:-- 'What a long tedious tiresome night! Nevertheless, it has saved us From the land of Kufr (disbelief).' I had a slave who ran away from me on the way. When I went to the Prophet (ﷺ) and gave the pledge of allegiance for embracing Islam, the slave showed up while I was still with the Prophet (ﷺ) who remarked, "O Abu Huraira! Here is your slave!" I said, "I manumit him for Allah's Sake," and so I freed him.

Sahih al-Bukhari Book 49, Hadith 15 Next Hadith → `Utba bin Abi Waqqas authorized his brother Sa`d bin Abi Waqqas to take the son of the slave-girl of Zam`a into his custody, telling him that the boy was his own (illegal) son. When Allah's Messenger (ﷺ) went (to Mecca) at the time of the Conquest, Sa`d took the son of the slave-girl of Zam`a to Allah's Messenger (ﷺ) and also brought 'Abu bin Zam`a with him and said, "O Allah's Messenger (ﷺ)! This is the son of my brother `Utba who authorized me to take him into my custody." 'Abu bin Zam`a said, "O Allah's Messenger (ﷺ)! He is my brother, the son of Zam`a's slave-girl and he was born on his bed." Allah's Messenger (ﷺ) looked at the son of the slave-girl of Zam`a and noticed much resemblance (to `Utba). Allah's Messenger (ﷺ) said, "It is for you, O 'Abu bin Zam`a as he was born on the bed of your father." Allah's Messenger (ﷺ) then told Sauda bint Zam`a to observe veil in the presence of the boy as he noticed the boy's resemblance to `Utba and Sauda was the wife of the Prophet (ﷺ) .
