Can a woman suffering istihaadah or a person who is incontinent pray Taraweeh with the wudoo’ for ‘Isha’ even if half of the night has passed?
Question

                Is it permissible for a woman suffering istihaadah (non-menstrual bleeding) to pray qiyaam al-layl when half of the night has passed with the wudoo’ of ‘Isha’?.
Praise be to Allah.
      This issue is the subject of a difference of scholarly 
      opinion. Some scholars are of the view that when half of the night has 
      passed, it is obligatory for her to renew her wudoo’. And it was said that 
      she does not have to renew her wudoo’, and this is more likely to be 
      correct. End quote.
