Abu Huraira said that Allah's Messenger ﷺ forbade that a woman should be married to one who had married her paternal aunt, or a paternal aunt to one who had married her brother’s daughter, or a woman to one who had married her maternal aunt, or a maternal aunt to one who had married her sister's daughter. A younger sister must not be married to one who has married an elder sister, nor an elder sister to one who has married a younger sister. Tirmidhi, Abu Dawud, Darimi and Nasa’i transmitted it, Nasa’i’s version ending with “her sister’s daughter.”
