It is narrated from Alqamah that a case regarding paternal brothers and the mother was brought to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). He gave one-third to the paternal brothers, and the rest of the wealth to the mother, and said: Whoever (among the deceased's heirs) has no 'Asabah (male agnatic heir), the mother will be considered his 'Asabah.
