Hazrat Anas (may Allah be pleased with him) narrates that Hazrat Abu Bakr was riding behind the Prophet صلی اللہ علیہ وسلم from Makkah to Madinah, and Hazrat Abu Bakr used to travel to and from Syria and was well-known, whereas the Prophet صلی اللہ علیہ وسلم was not so well-known. So people would say, "O Abu Bakr! Who is this young man with you?" He would reply, "He is a guide who is showing me the way." When they neared Madinah, they stopped at the place of Harrah and sent a message to the Ansar, so they came. He says, "I saw the Prophet صلی اللہ علیہ وسلم on the day he entered Madinah. I have not seen any day better and brighter than the day he came to us, and I saw him on the day he passed away, and I have not seen any day worse and darker than the day he passed away. May Allah's mercy and pleasure be upon him."
