When the Prophet (peace and blessings be upon him) recited the Quran in prayer, was a weeping or groaning sound heard from him?

The doctrines of the jurists regarding crying in prayer can be summarized as follows: The Hanafis believe that crying due to pain or calamity invalidates the prayer, whereas crying due to the remembrance of Paradise or Hell does not invalidate it. The Malikis hold that crying without a sound does not invalidate the prayer at all. However, crying with a sound invalidates it if it is voluntary, but it does not invalidate it if it is involuntary and due to humility (khushu'). As for the Shafi'is, the most correct view among them is that the appearance of two letters from crying invalidates the prayer. Meanwhile, the Hanbalis believe that the appearance of two letters from crying or groaning out of fear does not invalidate the prayer, because it is considered akin to remembrance (dhikr).
