Is it true that what was mentioned above—that Tasbeeh, "the number of His creation, the ink of His words, the pleasure of His Self, and the weight of His Throne," recited three times, earns a great reward; that saying "O Allah, forgive the Muslim men and Muslim women, the believing men and believing women, those who are alive among them and those who have died," earns a good deed for every Muslim man and Muslim woman; and that reciting Surat Al-Ikhlas three times earns the reward of reciting the entire Qur'an—is all this true?

The first dhikr mentioned in the question is correct: "Subhanallahi wa bihamdihi, adada khalqihi, wa ridha nafsihi, wa zinata 'arshihi, wa midada kalimatihi" (Glorified is Allah and praised is He, to the number of His creation, to the extent of His pleasure, to the weight of His Throne, and to the ink of His words). It is recommended to say this three times after the Fajr prayer. However, regarding the claim that one receives a good deed for every Muslim man and woman if they recite the aforementioned supplication, we know of no basis for it. As for the virtue of reciting Surat Al-Ikhlas, it is authentically reported in Al-Bukhari and Muslim that it is equivalent to one-third of the Quran. Whoever recites it three times sincerely, it is hoped that they will be granted the reward of reciting the entire Quran.
