To what extent is it true that for one who desires a righteous vision, it is recommended to be truthful, to sleep in a state of ritual purity (wudu') on one's right side, to recite Surahs "Ash-Shams," "Al-Layl," "At-Tin," "Al-Ikhlas," and "Al-Mu'awwidhatayn," and then to supplicate: "O Allah, I seek refuge in You from evil dreams, and I seek Your protection from the devil's tampering in wakefulness and sleep. O Allah, I ask You for a righteous, truthful, beneficial, and well-preserved vision that is not forgotten. O Allah, show me in my sleep what I love"?

The imams of dream interpretation mentioned that among the etiquettes of the one who sees a dream are: truthful speech, sleeping on ablution (wudu') on the right side, reciting certain surahs such as Ash-Shams, Al-Layl, At-Tin, Al-Ikhlas, and Al-Mu'awwidhatayn, and some supplications. Among its etiquettes is also not to narrate it to a woman, an enemy, or an ignorant person. Among the etiquettes of the interpreter are: not to interpret it at sunrise, nor at sunset, nor at midday (zawwal), nor at night. Some of this discourse was not reported in the elevated (marfu') hadiths, but rather it is from the sayings of the scholars of interpretation. They only mentioned these etiquettes because sleeping in a state of purity and on the right side is from the Sunnah and among the reasons for avoiding the manipulation of Satan. If a person is truthful in speech and sleeps in a state of purity and on their right side, then what they see in their sleep is usually a true vision (ru'ya) and not a mere dream (hulm).
