سَنُقْرِئُكَ فَلَا تَنسَى? إِلَّا مَا شَاءَ اللَّهُAslamualykum is this duaa prayed 7 times for weak memory?Is this authentic.Jazakallah Khairan

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

It was not reported in the Sharee‘ah texts that reciting this verse seven times, more or less, cures weak memory. We do not know from real-life experience that reciting this verse boosts weak memory. There is no doubt that the Quran is a source of healing and mercy for believers. It is a cure for all physical diseases, and those of the heart, mind, and soul. There is no doubt that the Ruqyah is effective, but specifying certain verses to be recited and repeated certain times to cure specific diseases and believing it to be an act prescribed by the Sharee‘ah, has no basis in the Sunnah. The view we adopt in Islamweb is that compliance with the reported texts is obligatory when it comes to the Ruqyah. Proving the permissibility of specifying certain verses to be recited in the Ruqyah as described based on real-life experience is invalid for many reasons, as detailed in a previous Fatwa posted on the Arabic website. Some of these reasons are as follows:

1) Declaring a certain act or considering it a (prescribed act and) part of the religion requires supportive texts from the Quran and Sunnah.

2) Relying on real-life experiences in determining the prescribed acts implies forsaking what is prescribed. When a sick person relies on real-life experiences and tried ways of treatment, it leads to forsaking the prescribed Ruqyah.

3) Reliance on real-life experiences (and tried ways of treatment) leads to attributing inconceivable medical treatments to the Sharee‘ah, while it is devoid of falsehood.

4) Reliance on real-life experience (and tried ways of treatment) implies modifying the provisions prescribed by the Law Maker (Allah) and attributing to Islam unprescribed acts that have no basis in the Sharee‘ah, which is considered Bid‘ah (religious innovation).

Allah knows best.
