Does the prayer of one who is praying while holding back the two excretions become invalid?

Question:
May Allah reward you. Honorable Shaykh, regarding the saying of the Prophet (peace and blessings be upon him), "There is no prayer for one who is holding back the two excretions," does the prayer become invalid? And if it does not become invalid, what is the explanation for this negation?

Answer:
Yes, it does not become invalid. The explanation for this negation is that the negation here is not regarding validity, but rather regarding perfection. The evidence is his saying (peace and blessings be upon him): "If any one of you feels something in his stomach, his prayer is not invalidated except by the certain breaking of his ablution." Yes. However, it is disliked for one to pray while holding back the two excretions; it is disliked for him to enter into prayer while holding back the two excretions. But if he enters into prayer and he has nothing, but something occurs in him during the prayer, this does not affect him; he completes his prayer and it is not disliked. Yes.
