Can't call it the best of Faraz, but certainly two of my favourite verses:
Aur abb yeh saari mataa-e-hasti...
yeh phool yeh zakhm bhi tere heiN
Yeh dukh ke nohey, yeh sukh ke naghme...
Jo kall mere thei woh abb tere heiN
Jo teri qurbat teri judayi...
mey katt gaye roz-o-shabb tere heiN
Na puuch uus ka ke woh deewana... bohut dinoN ka ujarh chuka hai
Woh kohkann tow nahiN tha lekin... kari chataanoN se larh chuka hai
Woh thak chuka thaa aur us ka taisha... usee ke seeney meyN garh chuka hai
