Musnad Ahmad 26:273

Abu Ahmad narrated to us, Aban bin Abdullah al-Bajali narrated to us, from Karim bin Abi Hazim, from his grandmother Salma bint Jabir, that her husband was martyred. She came to Abdullah bin Mas’ud and said: "I am a woman whose husband has been martyred, and men have proposed to me, but I have refused to marry until I meet him. Do you hope that if I am reunited with him, I will be among his wives?" He said: "Yes." A man said to him: "We have not seen you do this since we have been sitting with you." He said: "I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: 'The fastest of my nation to join me in Paradise is a woman from [the tribe of] Ahmas.'"
