Musnad Ahmad 27:1218

Abu al-Nadr narrated to us, Abu Mu'awiyah—meaning Shayban—narrated to us, from Layth, from Mujahid, from Abdullah ibn Umar, who said: A funeral procession passed by us, and Ibn Umar said: "If you would stand with us along with it." He said: So he took my hand and gripped it firmly. When we drew near to the graveyards, he heard a wailing sound from behind him while he was still gripping my hand. He turned me around and faced her, and he spoke harshly to her and said: "The Messenger of Allah (ﷺ) forbade that a funeral be followed by one that has wailing with it."
