Conditions for the Acceptance of Supplication

Question:
This dhikr and this du'a' are a weapon, meaning the Muslim is always negligent of it. Honorable Shaykh, they say that du'a' is the believer's weapon. Are there conditions required for this du'a' to be accepted?

Answer:
Du'a' is accepted if it is sincere for Allah (Mighty and Majestic), and if it is a prescribed du'a' that contains no sin and no severing of family ties. Also, one should not rush for the response, saying, "I called and I called, but I was not answered." Rather, one should call upon Allah as He said (peace and blessings be upon him) Call upon Allah with a present heart, and not call upon Allah with a heedless, distracted heart, for du'a' is not answered from a heedless, distracted heart, as is in the hadith. Yes.
