Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned the following:
Once, a person came to me requesting a ta’weez which will make him punctual in performing his five daily salaah. I said to him, “My friend! The verses of the Qur’aan Majeed (used in a ta’weez) do contain some effect. However, I do not have knowledge of such a ta’weez whereby I will be able to cause a policeman to be put into the ta‘weez, and at each salaah time he will emerge, and with his stick, compel you to perform your salaah.
“Hence, instead of giving you a ta’weez, I can rather show you a remedy and exercise through which you will become punctual upon your salaah in just four days. However, this remedy will not prove beneficial for you by you merely enquiring about it and not following it. It will only prove beneficial for you if you diligently practice upon it.
“The remedy is that if you miss one salaah, then you should skip one meal. If you miss two salaah, then you should skip two meals. If you miss three salaah, then you should skip three meals. Likewise, if you miss four salaah, then you should skip four meals. Commence following this remedy and then see whether you will miss any salaah.”
The person to whom I mentioned this was sincere in his desire to become committed and punctual upon his salaah. Thus, he followed this procedure, and people mentioned that in just three to four days, he became punctual upon all his salaah.
