Musnad Ahmad 30:3216

Muhammad ibn Ja‘far narrated to us, he said: Hisham al-Qardusi narrated to us, from Muhammad, from Abu Hurayrah, from the Prophet, may God bless him and grant him peace, that he said: "None of you should propose to a woman to whom his brother has already proposed, nor should he bid against the bid of his brother. A woman should not be married [in a way that combines her] with her paternal aunt, nor with her maternal aunt. And a woman should not ask for the divorce of her sister [in faith] so that she may empty her dish [of what is in it], but rather she should marry, for she shall only have what God has written for her."
