Musnad Ahmad

Dawud bin Khalid bin Dinar says that he and a man from Banu Taym—whose name was Abu Yusuf—passed by Rabi’ah bin Abi Abdur Rahman. Abu Yusuf said to him, “We find with others such ahadith that we do not find with you?” He replied, “I also have many ahadith, but I heard Rabi’ah bin Hudair—who used to stay close to Sayyiduna Talhah (may Allah be pleased with him)—saying that he never heard Sayyiduna Talhah (may Allah be pleased with him) narrate anything from the Prophet (peace and blessings be upon him) except for one hadith. I asked him, ‘Which is that one hadith?’ So, according to Rabi’ah, Sayyiduna Talhah (may Allah be pleased with him) said: ‘Once we went out with the Prophet (peace and blessings be upon him). When we reached the place called Harrah Waqim (which is a mound in Madinah) and came near it, we saw some curved graves like bows. We asked, “O Messenger of Allah! Are these the graves of our brothers?” The Prophet (peace and blessings be upon him) said: “These are the graves of our companions.” Then we moved on, and when we reached the graves of the martyrs, the Prophet (peace and blessings be upon him) said: “These are the graves of our brothers.”’”
