English Translation
Narrated to us by Waki', who said: Sufyan narrated to us, from Mansur, from al-Sha'bi, from Umm Salamah, that the Prophet (peace and blessings be upon him), when he left his house, used to say: "In the name of Allah, I place my trust in Allah. O Allah, I seek refuge in You lest we slip or go astray, or wrong or be wronged, or act ignorantly or be treated ignorantly."
