فضالة بن أيوب عن سيف بن عميرة عن ابن مسكان عن عمار بن حيان قال: اخبرني أبو عبد الله ببر ابنه إسماعيل له وقال: ولقد كنت أحبه وقد ازداد لي حبا ان رسول الله صلى الله عليه وآله اتته أخت له من الرضاعة فلما ان نظر إليها سربها وبسط ردائه لها فاجلسها عليه ثم اقبل يحدثها ويضحك في وجهها ثم قامت فذهبت ثم جاء أخوها فلم يصنع به ما صنع بها فقيل يا رسول الله صنعت بأخته ما لم تصنع به وهو رجل فقال: لأنها كانت أبر بأبيها منه.
3.Faḍālah ibn Ayyūb narrated from Sayf ibn ʿAmīrah, from Ibn Muskān, from ʿAmmār ibn Ḥayyān who  said, “I was informed by Abū ʿAbdillāh about the dutifulness of his son Ismāʿīl towards him. He said, ‘I used to love him, and now my love for him has increased. Verily the Messenger of Allah (ṣ) was visited by his foster sister. When he saw her, he was pleased and spread out his cloak for her and made her sit on it. Then he began speaking with her and smiling at her. Later, she stood up and left. Subsequently, her brother came [to visit him] but he did not treat him as he had treated her. Someone asked, “O Messenger of Allah, you treated his sister in a different way than how you treated him while he is a man?” He replied, “Because she was more dutiful to her father than him.”’”
