Does the Friday Prayer become void if the congregant intends to pray with the Imam, then the ablution of one of them (the Imam or the congregant) is nullified, so the worshiper becomes an individual performer before completing the prayer?

Ibn Hazm is of the opinion that Friday prayer can be established with two people. Among what he mentioned is that if someone begins the Friday prayer alone and then others join him before the rukoo' (bowing) of the first raka'ah, his prayer transforms into a two-raka'ah Friday prayer. However, if they join after the rukoo', he should interrupt his prayer and start it as a Friday prayer. He also stated that the Friday prayer must be performed in congregation; otherwise, it is a Dhuhr prayer of four raka'ahs.
