Is the prostration of gratitude prescribed for one who is in a state of minor or major ritual impurity?

Question:
May Allah reward you, Honorable Shaykh. Is the prostration of gratitude prescribed for one who has not performed ablution, or for one in a state of major ritual impurity, a menstruating woman, a woman with post-natal bleeding, or a woman with irregular non-menstrual bleeding?

Answer:
No, the prostration of gratitude is not performed by one who is in a state of major ritual impurity. The prostration of gratitude is not performed because prostration is a type of prayer, and ritual purity is a condition for it. According to some scholars, if it is permissible for him to recite the Qur'an, such as one who is in a state of minor ritual impurity, then it is permissible for him to recite the Qur'an from memory. In that case, if he comes upon a prostration verse, he prostrates. It is recommended for him to prostrate in response to the recitation of the prostration verse. However, the first opinion is that he does not prostrate, because the prostration of recitation is a type of prayer, so the conditions required for prayer are required for it.
