Stop. Get to know the Companions, the scholars, and the prominent figures. A new challenge: Who am I? I am one of the younger Companions, from the youth of the Ansar. I was born ten years before the Hijrah. I sought to join the Messenger of Allah, peace be upon him, on the day of Badr. He turned me away, but permitted me to join on the day of the Trench. I witnessed fifteen military expeditions with him. And I traveled with him eighteen times. I was also among the scholars and jurists of the Companions. I narrated three hundred and five hadiths from the Prophet, peace be upon him. The Messenger of Allah, peace be upon him, met me once. He took my hand and shook it. I said, "O Messenger of Allah, I thought shaking hands was only a practice of the non-Arabs." He replied, "We are more entitled to shaking hands than they are." "There are no two Muslims who meet and shake hands, but their sins fall away between them." I was keen to shake hands after that. And I would say, "It is part of the perfection of greeting that you shake your brother's hand." Abu Bakr, may Allah be pleased with him, came one day to my father at our house. He bought a camel saddle from him. He asked my father if I could carry his belongings. So I carried them with him. When we set out, I said, "O Abu Bakr, tell me how you both managed when you migrated with the Messenger of Allah, peace be upon him." He said, "Yes. We traveled through the night and the next day, until the midday heat peaked. The road was deserted, with no one passing through it. I saw a large rock that provided shade. We stopped there. I smoothed out a place with my hands for the Prophet, peace be upon him, to sleep. I spread a fur over it. I said, 'Sleep, O Messenger of Allah,' 'while I keep watch around you.' He slept, and I went out to keep watch around him. Suddenly, I saw a shepherd approaching the rock with his sheep, wanting from it the same thing we had wanted. I said to him, 'To whom do you belong, young man?' He said, 'To a man from the people of Makkah.' I said, 'Is there milk in your sheep?' He said, 'Yes.' I said, 'Will you milk them?' He said, 'Yes.' He took a sheep, and milked it for us. I brought it to the Prophet, peace be upon him, and I disliked waking him up. I found him awake just as I arrived. I poured some water onto the milk, until the bottom of it cooled. Then I said, 'Drink, O Messenger of Allah.' He drank until I was satisfied. Then I said, 'Is it not time to depart?' He said, 'Yes.' So we departed after the sun had begun to decline." I was known for my horsemanship and my courage, and for not fearing death. I killed one hundred men in single combat, not counting those in general battles. I participated in the conquest of Tustar. I was the commander of the force that conquered Rayy, in the year twenty-four of the Hijrah. So, who am I? Post the correct answer in the comments. Upon the release of the next episode, if Allah wills.
