Musannaf Ibn Abi Shayba 34:215

Yazid narrated to us, [he said] Ibn Abi Khalid informed us, from Ishaq bin Rashid, from a woman of the Ansar who is called Asma bint Yazid bin al-Sakan, that the Prophet, may God bless him and grant him peace, said to Umm Sa'd: "Will your tear not cease and your sadness not depart? For your son is the first one for whom God laughed and for whom the Throne shook."
