It is narrated from Imam Sha’bi (may Allah have mercy on him) that Sayyiduna Ali and Sayyiduna Zaid (may Allah be pleased with them both) said: When the grandmothers are of the same degree, then three grandmothers will inherit: two are the paternal grandmothers, that is, the father’s mother and the father’s mother’s mother, and the third is the maternal grandmother’s mother. Whichever of them is closer, it will be for «سهم ذوي القربي» .

It is narrated from (Ibn Shihab) Zuhri, may Allah have mercy on him, that Sayyiduna Uthman, may Allah be pleased with him, would not give the grandmother a share of inheritance in the presence of her son.
