“A man once asked abu Ja‘far (a.s.), about two sisters and a husband. He (the Imam) said, ‘It is half and half.’ The man then said, ‘I pray to Allah to keep you well, Allah has mentioned their share to be more than that. Their share is two-thirds.’ He then asked, ‘What do you say about a brother and husband?’ He (the Imam) said, ‘It is half and half.’ He asked, ‘Has Allah not given the entire legacy, saying, “. . . and he inherits her if she has no children.”?”’
