Explanation of Ibn Qayyim’s Thirteen Conditions for an Accepted Dua

The Lord of all creation loves those who ask, and He promised them that He would answer their du'a, and that He would make their hopes come true, and that He would give them what they ask for (fulfill their request); as long as they fulfill the statutory conditions when making their du'a and any preventative factors are removed. The text from the Book of Allaah and the Sunnah of the Messenger of Allaah (peace and blessings of Allaah be upon him) shows that the supplication described as not being rejected has criteria.
In fact, many texts in the Book of Allaah and the Sunnah of the Messenger of Allaah (peace and blessings of Allaah be upon him) show that the accepted du'a has rules that are necessary for the one making the du'a to be diligent in following them when making his du'a. Likewise, there are preventive factors that he must take care of so that his du'a is not rejected. Its explanations have come in the Book of Allaah and the Sunnah of His Prophet (peace and blessings of Allaah be upon him).
The scholars have called them: the conditions and etiquettes of supplicating. And they are extremely important. It is befitting for the one supplicating while supplicating to be intent on carrying out the etiquettes of supplicating so that his supplication is answered. And to be aware of the affairs that prevent it from being accepted so his supplication won't be rejected.
