Sunan an-Nasa'i 1344

Muhammad ibn Ishaq al-Saghani informed us; he said: Abu Salamah al-Khuza‘i—Mansur ibn Salamah—narrated to us; he said: Khallad ibn Sulayman narrated to us. Abu Salamah said—and he was one of the fearful ones—from Khalid ibn Abi ‘Imran, from ‘Urwah, from ‘A’ishah, that whenever the Messenger of Allah (peace and blessings be upon him) sat in a gathering or prayed, he would say some words. ‘A’ishah asked him about them, and he said: “If he has spoken good, they seal it for him until the Day of Resurrection; and if he has spoken otherwise, they are an expiation for him: Glory and praise be to You, O Allah; I seek Your forgiveness and turn to You in repentance.”
