The scholarly duel between Brother Juwaid and Dawood is stunning for their efforts which would have won them Nobel Laurel if they would have analysed any natural phenomena of Allah instead of their efforts to score points over wordily engagement. Allah revealed Quran in Arabic for the Pagan Arabs of the time but its message is universal hence need to considered in universal perspective for human benefit in all inclusive language of nature (science) . And Quran is replete with verses that its meaning/words has been twisted at all the time ( 12:40, 53:23, 7:71, 3:78 2:79).
It is brilliant debate of Lexicographers who analyzing Arabic word to justify their point. In the bargain, it is undermining the authority of Allah by telling Him that He does not know his creation and nature. The natural phenomena are His word/signs/Ayats of ALLAH that must be subjected to human benefits. The so called rituals (salaat, Haj , fasts & Zakat etc ) are pre-Quranic traditions of forefathers and continued even at the time of prophet (sa). The people at the time were not aware that Sun/Moon rise/setting varies at every place (latitude/altitude) differently and even it does not rise/set for days/months at some region, then how can Allah fix static rituals based on Sun/Moon ? Is it not blasphemous to discuss/argue of Allah's wisdom on the word which has no clear meaning and keep on dissecting in huge volumes ? Even to discuss the word salaat/Salwat/sallu ( whatever it means to Arab linguistic - as it has meant by Arabs from ritual, fire, join, blessing to synagogues) This means Allah is not even consistent to know his compilation!!!! I hope we concentrate the overall message of Quran for human benefit. Only Allah knows the proper meanings but nature as sign/verse of Allah has only one meaning almost to be analysed, dissect, scrutinized with human faculties with confirmed result.
Sorry it is not personal skepticism to your brilliance - but feel sad that Arab linguists feel their right to analyse words excluding all the humanity and non-Arabic feel as left out by Allah!!! This cannot be.
