The Quran
Surah 4 An-Nisa' Ayat 95 - The Women
لايستوي القاعدون من المؤمنين غير اولى الضرر والمجاهدون في سبيل الله باموالهم وانفسهم فضل الله المجاهدين باموالهم وانفسهم على القاعدين درجة وكلا وعد الله الحسنى وفضل الله المجاهدين على القاعدين اجرا عظيما
"SUCH of the believers as remain passive - other than the disabled - cannot be deemed equal to those who strive hard in God's cause with their possessions and their lives: God has exalted those who strive hard with their possessions and their lives far above those who remain passive. Although God has promised the ultimate good unto all [believers], yet has God exalted those who strive hard above those who remain passive by [promising them] a mighty reward"
