3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhassin ibn Ahmad from Aban ibn ‘Uthman from Fadl abu al-‘Abbas al-Baqbaq who has narrated the following: “I once asked abu ‘Abd Allah , about the case of both parents and two sisters from both parents; if they bar the mother from one-third of the legacy. He (the Imam) said, ‘No, they do not do so.’ I then asked, ‘What happens if they are three?’ He (the Imam) said, ‘No, they do not do so.’ I then asked, ‘What happens if they are four?’ He (the Imam) said, ‘Yes, they bar her from one-third.’”
