Yazid bin Hurmuz reported,

Najdah bin Amir wrote to Ibn Abbas asking him about several matters. I was present with Ibn Abbas when he read the letter and when he wrote his reply.Ibn Abbas said, "By Allah, were it not to prevent him from falling into evil, I would not have written to him at all, not even out of courtesy."He then wrote to him, "You asked me about the share of the near relatives whom Allah mentioned, who they are. We used to consider that they were the close relatives of the Messenger of Allah, but our people refused to grant us that.You asked me about the orphan, when his orphanhood ends. When he reaches the age of marriage and shows sound judgment, his property is handed over to him and his orphanhood has ended.You asked whether the Messenger of Allah ﷺ used to kill any of the children of the polytheists. The Messenger of Allah ﷺ did not kill any of them, and you too must not kill them, unless you know about a child what Khidr knew about the boy he killed.You asked about the woman and the slave, whether they had a fixed share when they were present in battle. They had no fixed share, but they would be given something from the spoils of the Muslims."

عن يزيد بن هرمز قال

كتب نجدة بن عامر إلى ابن عباس يسأله عن أشياء فشهدت ابن عباس حين قرأ كتابه وحين كتب جوابه فقال ابن عباس والله لولا أن أرده عن شر يقع فيه ما كتبت إليه ولا نعمة عين قال فكتب إليه إنك سألتني عن سهم ذوي القربى الذي ذكر الله عز وجل من هم وإنا كنا نرى قرابة رسول الله هم فأبى ذلك علينا قومنا وسأله عن اليتيم متى ينقضي يتمه وإنه إذا بلغ النكاح وأونس منه رشد دفع إليه ماله وقد انقضى يتمه وسأله هل كان رسول الله ﷺ يقتل من صبيان المشركين أحدا فقال إن رسول الله ﷺ لم يقتل منهم أحدا وأنت فلا تقتل إلا أن تكون تعلم ما علم الخضر من الغلام الذي قتله وسأله عن المرأة والعبد هل كان لهما سهم معلوم إذا حضروا البأس وإنه لم يكن لهم سهم معلوم إلا أن يحذيا من غنائم المسلمين
