Recite it 3 times after Farj
Once the Prophet (SAW) left to pray Fajr Salat from (his wife's home) while she was offering prayer. When he (SAW) returned after Ishraq prayer, she was still sitting on her prayer carpet. On this he (SAW) said to her: "Have you been continuously sitting in the same place since I left you?" She replied, "Yes." Thereupon he (SAW) said: "After I left you, I have recited four sentences three times; and if they could be measured against what you have recited since morning they would prove weightier. These four sentences are:
سبحان الله وبحمده عدد خلقه, ورضا نفسه, وزنة عرشه, ومداد كلماته
(Glory be to Allah and praise is due to Him, according to the number of His creation and according to His pleasure and corresponding to the weight of His Throne and as much as the ink [used in recording] His words).
