No matter what happens in life, 
 there's always a reason.
مهما حدث في الحياة، هنالك سببٌ دوماً
Was auch im Leben geschieht,
alles hat einen Grund.
No importa qué ocurra en la vida,
siempre es por algo.
No importa qué ocurra en la vida,
siempre hay una razón.
Quoi qu’il arrive dans ce monde,
tout a une raison.
Qualsiasi cosa accada nella vita, c'è sempre un motivo.
Não importa o que aconteça,
sempre existe um motivo.
Что бы ни происходило,
всему есть причина.
