The Ruling on Praying While Urged to Defecate

Question:
Finally, regarding the one who is straining, O Shaykh, the condition is: if he fears that he will miss the prayer, does he pray while straining?
Answer:
No, it is not permissible; it is disliked, because this removes khushu' (humility). One who is straining or has an urgent need to relieve himself is not permitted to enter the prayer in this state, because his mind becomes distracted and he does not achieve khushu' in the prayer. Rather, he should first relieve himself of these matters, then perform wudu' and pray, even if he misses the congregational prayer.
