If music of that naat is used before in any film then it should not be allowed.Let me tell you an authentic incident from Islamic history. When our great Prophet Muhammad (SAW) entered Madina,the little girls of Madina were playing tambourine(daff)and were singing these lines in praise of Prophet (SAW).
"Tala al badar-o-aleina min sania til Wida,waja baat shukur-o- aleina,ma da allah-e- da"
It means musical naa't is not forbidden in a respectable and reasonable musical background.Only that music which is normally called jampacked music is not allowed.It would be an insulting act to use filmi music in composition of naa't.If you have to compose a musical naa't then follow the example of girls of Madina who played tambourine which is a kind of musical instrument.They played tambourine and sung in praise of Prophet(SAW) and we are completely aware about this naa't which was sung by that time;
" THE MOON AROSE FROM "THE PASSES OF WIDA" AND PROPHET(SAW) CAME HERE , EVERY ONE SHOULD THANKED TO HIS LORD WHO HAS BLESSED US AND BESTOWED UPON US SUCH A GREAT BLESSING IN THE FORM OF PROPHET (SAW)"
Melaad-un -Nabi(saw) which are being celebrated at present time are a mere show of music and dance only.No one can even suppose to consider it as a sacred gathering of Melaad.To celebrate this event is not prohibited but the way it is celebrated nowadays is improper.It should be celebrated in a decent manner;though every one give his own judgment according to his standards of decency.May Allah bless us to be on right direction.
