It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that Sayyiduna Abu Bakr (may Allah be pleased with him) married Sayyidah Asma' bint Umays (may Allah be pleased with her) after Sayyiduna Ja'far bin Abi Talib (may Allah be pleased with him). Then he came to go in to Sayyidah Asma' (may Allah be pleased with her) and saw some people sitting in her house. So he went back to the Prophet of Allah (peace and blessings be upon him) and told him. He (peace and blessings be upon him) said: "Abu Bakr, what is the matter?" He said: "I did not see anything wrong." So the Messenger of Allah (peace and blessings be upon him) said: "Allah has kept her free of that." Then the Prophet of Allah (peace and blessings be upon him) stood up and said: "No man should go in to a woman whose husband is away from home, unless someone else is with him."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith was narrated from Jubayr bin Nufayr (may Allah have mercy on him) only by Bakr bin Sawadah (may Allah have mercy on him), and from Bakr (may Allah have mercy on him) only by Ja'far (may Allah have mercy on him); al-Layth (may Allah have mercy on him) is alone in narrating it."
