Ubayd al-Himyari states: I was with Sayyiduna Uthman (may Allah be pleased with him); this was at the time when he had been besieged. He asked: "Is Talhah here?" Sayyiduna Talhah (may Allah be pleased with him) said: "Yes!" Sayyiduna Uthman (may Allah be pleased with him) said: "Stand up." Then Sayyiduna Uthman (may Allah be pleased with him) said: "I ask you by Allah: do you not know that we were with the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: 'Let each one of you take the hand of the one sitting beside him.' So you took the hand of so-and-so, and so-and-so took the hand of so-and-so, until every person had taken the hand of his companion, and the Prophet (peace and blessings be upon him) took my hand and said: 'This is my companion in this world, and he will be my close companion in the Hereafter.'" Sayyiduna Talhah (may Allah be pleased with him) replied: "Allah knows, yes."
Al-Bazzar recorded it. Its chain contains a narrator, Kharijah bin Mus'ab, who is matruk (abandoned); it has been said of him that he is a liar, and one view about him is that he is mustaqim al-hadith (sound in hadith); the Imams, such as Ahmad and others, declared him da'if (weak).
