ANSWER:

No problem in this whatsoever. You can even drink coffee or tea.

During Ramadan I pray taraweeh at home and usually I extend my Quran recitation. So my throats become sore and dry. Is it permissible after giving salam for the two units of Salat to drink water and after resume the Salat?

Taraweeh, Tahajjud and Qiyam-ul-Layl |
