Jami` at-Tirmidhi Book 48, Hadith 184
“Whoever says ten times: ‘None has the right to be worshipped by Allah, Alone, without partner, to Him belongs all that exists, and to Him belongs the praise, wa huwa `alā kulli shai’in qadīr)’ it is for him equal to freeing four slaves among the offspring of Isma`il.”
The Messenger of Allah (ﷺ) said: “Whoever supplicates against the one who wronged him has triumphed.”
“The Messenger of Allah (ﷺ) entered upon me and before me were four thousand date pits, I was making Tasbih with them. He said: ‘You have made Tasbih with these? Should I not teach you that which is more than what you have made Tasbih with?’ So I said: ‘Indeed, teach me.’ So he said: ‘Say: glory is to Allah according to the number of His creation (Subḥān Allāhi `adada khalqihi).’”
