In the given lines the poet compares the sweet voice of the girl to that of a nightingale. Nightingale is considered a sweet-voice bird. The poet says no nightingale has so far sung as melodious a song as the girl sings. When some group of tired travelers reaches a shady place, in the Arabian deserts, the nightingale welcomes the caravan with its sweet song. It is obvious that commonly there is no nightingale in the deserts. But if there is some oasis, it is but natural that a nightingale is found there. So when a tired caravan reaches any oasis or shrubby area the nightingale welcomes it. The poet says that the voice of the singing girl is rather sweeter than that of a nightingale
