یٰۤاَیُّهَا الَّذِیْنَ اٰمَنُوْا مَا لَكُمْ اِذَا قِیْلَ لَكُمُ انْفِرُوْا فِیْ سَبِیْلِ اللّٰهِ اثَّاقَلْتُمْ اِلَی الْاَرْضِ اَرَضِیْتُمْ بِالْحَیٰوةِ الدُّنْیَا مِنَ الْاٰخِرَةِ فَمَا مَتَاعُ الْحَیٰوةِ الدُّنْیَا فِی الْاٰخِرَةِ اِلَّا قَلِیْلٌ ۟

Yaaa aiyuhal lazeena aamanoo maa lakum izaa qeela lakumun firoo fee sabeelil laahis saaqaltum ilal ard; aradeetum bilhayaatid dunyaa minal Aakhirah; famaamataa'ul hayaatiddunyaa fil Aakhirati illaa qaleel

“O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of Allah, ye cling heavily to the earth? Do ye prefer the life of this world to the Hereafter? But little is the comfort of this life, as compared with the Hereafter.”

Quran 9:38 (Yusuf Ali Translation)
