It is narrated from Ikrimah that he says: Hazrat Ibn Abbas (may Allah be pleased with them) sent me to Hazrat Zaid bin Thabit (may Allah be pleased with him) to inquire about the issue of inheritance for the husband and parents. So Hazrat Zaid (may Allah be pleased with him) said that the husband gets half of the wealth, and the mother gets one third of the remaining wealth, and that will be one sixth of the total wealth. Hazrat Ibn Abbas (may Allah be pleased with them) sent a message to him asking, "Do you find this in the Book of Allah?" He replied, "I dislike giving preference to the mother over the father," and Hazrat Ibn Abbas (may Allah be pleased with them) used to give the mother one third of the entire wealth.
