Ata bin Yasar (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) rode to Quba, seeking Allah's guidance (istikharah) concerning the paternal aunt and the maternal aunt, and it was revealed to him (peace and blessings be upon him) that "there is no inheritance for them both."
