The wording of the stated Du`a' is not Mashru` (Islamically approved) and has no origin. Thus, it should not be said as Du`a' because there is no evidence supporting it, neither from the Qur'an nor the Sunnah (whatever is reported from the Prophet). Moreover, it includes some phrases which oppose the `Aqidah (creed), such as saying: Bismillah (In the Name of Allah) is our door; Tabarak is our walls; Ya-sin is our ceiling, Kaf- Ha-Ya-`Ayn-Sad is our sufficient means, and Ha-Mim. `Ayn-Sin-Qaf is our protective means... The curtain of the `Arsh is let down on us.Muslims are required to
recite Du`a's which are Mashru` and taken from the Qur'an and the Sunnah, and which were stated by the Salaf (righteous predecessors) in their books, such as the books entitled "Al-Adhkar" by
Al-Nawawy (may Allah be merciful to him), "Al-Wabil Al-Sayyib" by
Ibn Al-Qayyim (may Allah be merciful to him), and "Tuhfat Al-Akhyar" by his Eminence,
Shaykh `Abdul-`Aziz ibn Baz (may Allah protect him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
