la tas aluni nashid song

http://www.youtube.com/watch?v=nokNWQJP_ok
Jangan tanyakan aku tentang hidupku
Ia adalah sebuah rahsia kehidupan
Ia adalah anugerah
Ia adalah ujian
Ia adalah dunia yang penuh dgn cita2
Aku telah menjualnya kpd Allah
Kemudian aku berjalan dalam barisan para pembawa petunjuk
Jalan hidupku adalah Al-Quran, pedang dan ujian
Allah telah memberkatinya
dan para Nabi terdahulu telah melaluinya
Para syuhada telah menyirami jalan ini dgn darah mereka
Maka jadilah ia taman indah yg dikelilingi cahaya
Sedangkan penghujung perjalanankan ku adalah apa yang meredhakan Allah
dan apa yang diinginkanNya
Keuntungan dgn kemenangan nyata
Atau kesyahidan dan keabadian
Jika engkau telah berada di muka bumi
Dan engkau tahu bahawa umurmu terbatas
Maka jadilah pahlawan dan pembawa petunjuk
Jika tidak alangkah buruknya kewujudanmu
