Quotes

 * 'Amr b. Shu'aib on his father's authority said that his grandfather reported: The Prophet (ﷺ) decided regarding one who was treated as a member of a family after the death of his father, to whom he was attributed when the heirs said he was one of them, that if he was the child of a slave-woman whom the father owned when he had intercourse with her, he was included among those who sought his inclusion, but received none of the inheritance which was previously divided; he, however, received his portion of the inheritance which had not already been divided; but if the father to whom he was attributed had disowned him, he was not joined to the heirs. If he was a child of a slave-woman whom the father did not possess or of a free woman with whom he had illicit intercourse, he was not joined to the heirs and did not inherit even if the one to whom he was attributed is the one who claimed paternity, since he was a child of fornication whether his mother was free or a slave.
 * Sunan Abu Dawud 12:2258

Quran

 * If the deceased left children behind, each of the parents shall get one sixth of the estate, but if the deceased left no children and the parents are the only heirs, the mother shall get one third of the estate...""Sura 4:11


 * If a man or a woman is made an heir on account of his [or her] kalalah relationship [with the deceased] and he [or she] has one brother or sister, then the brother or sister shall receive a sixth, and if they be more than this, then they shall be sharers in one-third, after payment of any legacies bequeathed and any [outstanding] debts – without harming anyone. This is a command from God, and God is Gracious and All-Knowing." Qur'an, [Quran 4:12].


 * People ask your pronouncement. Say: God enjoins you about your kalalah heirs that if a man dies childless and he has only a sister, then she shall inherit half of what he leaves and if a sister dies childless, then her brother shall be her heir; and if there are two sisters, then they shall inherit two-thirds of what he [or she] leaves. If there are many brothers and sisters, then the share of each male shall be that of two females. God expounds unto you that you err not and God has knowledge of all things." Qur'an, [Quran 4:176].
