1. Ali ibn Ibrahim has narrated from his father from and Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad all from ibn Mahbub from ‘ Abd Allah ibn Sinan from ‘ Abd al- Rahman ibn Sayabah who has narrated the following: “A woman made a will to me that said, ‘With one-third of my legacy my debts must be paid and part of it will be for so and so female.’ I then asked ibn abu Layla’ about it and he said, ‘There is nothing for her because I do not know how much is al-Juz’ (a part).’ I then asked abu ‘Abd Allah (a.s.), about it afterwards and informed him (the Imam) how she had said it and what ibn abu Layla’ had said. He (the Imam) said, ‘Ibn abu Layla’ has spoken falsely. She can have one-tenth of the one- third because Allah, most Majestic, most Glorious, said to Ibrahim ‘Alayhi al-Salam, “Place Juza’ (a part) of it on every mountain” (2:260) the mountains at that time were ten, thus al-Juz’ is one-tenth of something.’”
