Ishaq bin Rashid narrates from a woman of the Ansar, Sayyidah Asma bint Yazid bin Sakan (may Allah be pleased with her), who said: When the bier of Sa'd (may Allah be pleased with him) was brought out, his mother cried out, and the Messenger of Allah (peace and blessings be upon him) said to her: "Will your tears not cease and your grief not go away? Indeed your son is the first person for whom Allah laughed, and for whom the Throne shook."
