It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade marrying a niece in the presence of her paternal aunt, or a paternal aunt in the presence of her niece, or a maternal niece in the presence of her maternal aunt, or a maternal aunt in the presence of her niece. And he said: Do not marry the younger in the presence of the elder, nor the elder in the presence of the younger.
