What is the ruling on making du'a' (supplication) for one's parents during the obligatory prayer?

Question : The questioner asks: Is it permissible to make du'a' for one's parents during the obligatory prayer?

Answer : It is better for the one praying, whether in voluntary or obligatory prayer, to focus on the supplications reported from the Prophet (peace and blessings be upon him), or for himself or for any of the Muslims, in both obligatory and voluntary prayers. However, if a person is praying behind an imam, he should not delay following the imam for the sake of making du'a', as we see some people do; you find them praying with the imam, prostrating, and striving to make du'a' to Allah in prostration.
Then the imam stands up and recites al-Fatihah or most of it, or perhaps he recites something with it, while this man is still prostrating, making du'a' to Allah the Exalted and Majestic. We say this is not correct, because if you are with the imam, you are commanded to follow him, based on the saying of your Prophet Muhammad (peace and blessings be upon him): "The imam is appointed to be followed, so do not differ with him." Then the Prophet (peace and blessings be upon him) detailed this by saying: . As for the person who prays alone, he may lengthen the prayer as much as he wishes in both obligatory and voluntary prayers, and he may make du'a' with whatever he wishes for himself and for others among the Muslims.
