Seeing oneself recite Surah Yunus or part of it, or hearing it recited over oneself, signifies broad and abundant provision.
Ja'far al-Sadiq said that the person's speech and worship will be beautiful and accepted. Sometimes God Most High grants the reciter knowledge and sound belief and keeps from him the schemes of deceivers and the magic of sorcerers.
Seeing and reciting this surah also signifies piety and scrupulousness.
