I swore by al-Lat and al-Uzza, so the Messenger of Allah ﷺ said, "Say, 'There is no god but Allah alone, He has no partner,' then spit lightly to your left three times, seek refuge with Allah, and do not do it again."
حدثنا علي بن محمد والحسن بن علي الخلال قالا حدثنا يحيى بن آدم عن إسرائيل عن أبي إسحق عن مصعب بن سعد
حلفت باللات والعزى فقال رسول الله ﷺ قل لا إله إلا الله وحده لا شريك له ثم انفث عن يسارك ثلاثا وتعوذ ولا تعد
[Sahih] Nasai narrated it in "Oaths and Vows, Swearing by Lat and Uzza," no. 3808, from the hadith of Abu Ishaq, through this same chain, and he explicitly stated that he heard it directly in one of Nasai's versions. Ibn Hibban also graded it sahih (Mawarid), no. 1178.
