It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he heard the Prophet (peace and blessings be upon him) say: "A paternal aunt is not to be combined in marriage with her brother's daughter, nor a maternal aunt with her sister's daughter."
Only Ibrahim bin al-Mundhir (may Allah have mercy on him) narrated this hadith from Ishaq bin Ja'far bin Muhammad (may Allah have mercy on him).
