Sahih Muslim · Hadith 1774

وحدثنا محمد بن المثنى، حدثنا معاذ بن هشام، حدثني أبي، عن قتادة، عن زرارة بن أوفى، عن سعد بن هشام، أنه طلق امرأته ثم انطلق إلى المدينة ليبيع عقاره ‏.‏ فذكر نحوه ‏.‏

Sa'd b. Hisham reported: I went to 'Abdullah b. 'Abbas and asked him about the Witr prayer, and the rest of the hadith is the same as recorded in this event. She (Hadrat 'A'isha) said: Who is that Hisham? I said: Son of 'Amir. She said: What a fine man 'Amir was! He died as a martyr in the Battle of Uhud.
