I received a message like this in my e-mail: Praying two rakâahs every Thursday during Shaâbaan: The Messenger (blessings and peace of Allah be upon him and his family) said: âWhoever prays two rakâahs at that time, reciting in each rakâah the Opening of the Book (al-Faatihah) and âQul Huwa Allahu Ahadâ (Soorat al-Ikhlaas) one hundred times, and when he says the salaam, he sends blessings upon the Prophet (blessings and peace of Allah be upon him) one hundred times, Allah will fulfil all his needs in his religious and worldly affairs.â I would like to find out how sound these words are and how to do these two rakâahs, seeing that it mentions reciting Qul Huwa Allahu Ahad one hundred times; is that recitation to be completed during the two rakâahs or afterwards?.
Praise be to Allaah.
This hadeeth has no basis in the books of Sunnah. It would appear to be one of the fabricated hadeeths that speak of the virtues of praying in Shabaan. A number of hadeeths were fabricated and falsely attributed to the Messenger (blessings and peace of Allah be upon him) about the virtues of Shabaan and pray during this month, and the night of the fifteenth of the month. Al-Allaamah Ibn Hajar al-Haytami (may Allah have mercy on him) said: All the hadeeths which speak of the virtues of this night - meaning the night of the first Friday of Rajab and the night of the fifteenth of Shabaan - are false and has no basis, even though they appear in some books by major scholars such as al-Ghazaali's Ihya' Uloom ad-Deen and so on.

Similarly, hadeeths were fabricated about the virtue of praying on certain days of the week.
Ash-Shawkaani (may Allah have mercy on him) said: With regard to what is said about praying on Sunday, Monday or other days of the week, there is no dispute among the scholars of hadeeth that these are fabricated hadeeths and that this prayer is not regarded as mustahabb by any of the leading scholars. End quote.

So it is not permissible to act upon this false and fabricated hadeeth. In the saheeh hadeeths there is sufficient for the one who wants to truly follow the Prophet (blessings and peace of Allah be upon him).
And Allah knows best.
