It is narrated from Sayyidah Asma' bint Yazid bin al-Sakan al-Ansariyyah (may Allah be pleased with her) that when Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him) passed away, his mother cried out and wept. The Messenger of Allah (peace and blessings be upon him) said to her: "Will your tears not dry and your grief not go away? Your son is the first person at whom Allah Almighty smiled (with pleasure) and for whom the Throne shook." This hadith has a sahih (authentic) chain of narration.
