Musannaf Ibn Abi Shayba 6:1146

Abu Dawud narrated to us, from Abdullah, [who] narrated to us, from Abd al-Aziz ibn Muhammad, from Muhammad ibn Zayd ibn al-Muhajir ibn Qunfudh, from Abdullah ibn Amir ibn Rabi'ah, from his father, who said: The Messenger of Allah (may Allah bless him and grant him peace) passed by a fresh grave and said, "What is this grave?" They said, "The grave of so-and-so [a woman]." He said, "Why did you not inform me?" Then he stood in rows over it and prayed over her.
