If one becomes aware of impurity in his garment during the time of prayer, does he exit his prayer or remove his garment?

The questioner : Shaykh, if one becomes aware of impurity during the prayer.

The Shaykh : What?

The questioner : If one becomes aware of impurity in his garment during the time of prayer, meaning he is inside the prayer and learns that his garment contains impurity, does he... remove his garment or is his prayer invalid?

The Shaykh : If one becomes aware of impurity during the prayer, it is obligatory for him to remove the impure garment if he has another garment to cover himself with. If he does not have another garment, let him continue in it. Yes, Ibrahim?
