They are the real winners despite all their sufferings, torture and martyrdom. Our life is not limited to this world but it goes on for our long future after this life, where we will see the results of our deeds. Allah Has Said in Quran : We Will definitely support our messengers and the believers in this worldly life and on the day of resurrection. (Sura Ghaafir, verse 51).
