Is it permissible to
perform salaah while zawwaal is approaching... 

With the result the
musalli starts his salaat before zawwaal and continues till after
zawwaal... 

This particularly
happens on Jumuah whilst performing salaatut tasbeeh... 

According to one
aalim.. He says there is no
zawwaal on Jumuah... So it's permissible... 

Answer: 

If the time of Zawāl comes in while one is performing Ṣalāh, the Ṣalāh will become nullified. (Fataawa Darul Uloom Deoband Vol. 2 Pg. 85). This is irrespective of whether it is the day of Jumu'ah or any other day, as the preferred view is that there is Zawāl on the day of Jumu'ah just like any other day. (Imdaadul Ahkaam Vol. 1 Pg. 408) 

AND ALLAH TA'AALA ALONE IN HIS INFINITE KNOWLEDGE KNOWS BEST
