survey on the Sanad and Text of Occasions of Revelation of al-Muawwidhatayn

One of the hadith about the occasions of revelation of surat al-Falaq and al-Nas is the saying by the Jewish Labid ibn Asam about magic of Prophet Muhammad (PBUH). According tothis hadith, a person called Labid ibn Asam bewitched Prophet Muhammad by blowing into eleven nodes and Prophet was sick because of this magic. Afterwards, God revealed surat al-Falaq and al-Nas to Prophet to heal him. The present research, which was carried out using the descriptive-analytical method, aimed at survey the “sand and text” of this hadiths in Shiite and Sunni sources. Investigations indicated that this hadith was mentioned in different hadith sources and exegetical sources of the two sects in different forms and all of these references suffer a weakness in sanad. In addition, the contents of these hadiths due to contradictions in their textual contents and conflict with the Quran, Prophet’s dignity, his infallibility, and historic facts, cause anxiety and distress and are not unreliable.
