Mus'ab bin Sa'd bin Abi Waqqas narrates from his father: I swore by Lat and 'Uzza, so my companions said to me: You have said a very wrong thing. I went to the service of the Prophet Muhammad (peace be upon him) and said: The time of ignorance is still near, and I (mistakenly) swore by Lat and 'Uzza. So the Prophet Muhammad (peace be upon him) said to me: Recite this three times, "There is no deity except Allah, He alone is the only deity." Spit to your left three times, blow, and seek refuge with Allah from Satan, and do not do this again.
