Is the prayer to be repeated if ablution is broken immediately after the salutation to the right?

The majority of jurists hold the second taslim (salutation) in prayer to be recommended (mustahabb). The Hanbalis, however, deem it obligatory in obligatory prayers, except for the funeral prayer and supererogatory prayers. Meanwhile, more than one scholar has narrated a consensus (ijma') that the second taslim is not obligatory. If one completes the first taslim and then his ablution is invalidated, his prayer is valid, and he is not required to repeat it, according to the more preponderant opinion. However, if his ablution is invalidated before completing the first taslim, his prayer is invalid, and he must repeat it.
