Is the sending of blessings upon the Prophet a condition for the acceptance of supplication?

Question : Is supplication obstructed if I do not send blessings upon the Prophet (peace and blessings be upon him) at its beginning and end?

Answer : It is not obstructed. That is, a person may supplicate to Allah (Mighty and Majestic) even if the sending of blessings upon the Prophet (peace and blessings be upon him) does not precede it or follow it. However, it is better to conclude the supplication with the sending of blessings upon the Prophet (peace and blessings be upon him) and to begin it with praise to Allah (Mighty and Majestic) and the sending of blessings upon His Prophet (peace and blessings be upon him).
