Hadith.1192 - Ali ibn Ja'far asked his brother Imam Musa ibn Jafar Al-Kadhim (as) about a man who is behind an Imam and the Imam prolongs the tashahhud, causing the man to feel the urge to urinate, fear missing something, or experience pain. What should he do?
Imam (as) replied: "He should perform the taslim (salutation of peace), leave, and leave the Imam."
