Wahai Tuhan......
Ya Allah....aku redha sekiranya ini ujianMu terhadapku..sesungguhnya Engkau lebih Maha mengetahui apa yang terbaik untukku. Tidak akan Engkau turunkan ujian ini sekiranya hambaMu ini tidak mampu mengharunginya..Yang Maha Menngasihani...aku redha ya Allah..aku redha ya Allah..
Ya Allah..Yang Maha Bijaksana
Sesungguhnya Engkau Maha Mengetahui insan insan yang telah menganiaya hambaMu ini Ya Allah...Engkau tunjukkanlah mereka jalan kebenaran..dan sesungguhnya Ya Allah..tidak hambaMu ini halalkan segala perlakuan dan setiap penganiayaan/setiap ringgit dan sen yang telah dilakukan terhadap ku Ya Allah..aku pasrah ya Allah..
Ya Allah rabbul A'lamin...
Engkau lindungilah keluargaku dari segala musibah..Engkau didiklah hati hati ini dengan ketakwaan kepadaMu ya Allah...Takut kepada Pencipta, cinta kepada Rasul dan bangga pada agamaku...Lindungilah kami dari melakukan dosa Ya Allah...dan janganlah Engkau Ya Allah menarik kenikmatan ketika hati bertasbih dan menyebut namaMu Ya Allah...sesungguhnya itulah kelazatan yang tidak terhingga di muka bumi ini Ya Allah
Amin Ya Rabbal A'lamin

When we talk about life..there's lot of options/decisions that need to deal with..this will determine what might be happened next...have u make a good decision to decide yours? Me?
Yes..I did it when it needed. When making a decision, there's a lot of consideration that need to be taken care of...people that u love,surrounding that makes u happy,people's feeling and so on..
Lots of things happened in my life...good and bad...but I do believe ...each of them happened for a reason and sake.
Anyway, once u make it, deal with it. Look forward and do not flip back...there's always good things happened along the journey...take it easy...enjoy your life. Sacrifice?...Yup...it's a must even if it is a win win situation.There's always a price to pay toward anything happened..deal with it...
At the end of the day....I have to leave the people that i love so that I can go along the journey alone to gain maturity and part of life lesson
