إِنَّمَا الحَيَاةُ الدُّنْيَا لَعِبٌ وَلَهْوٌ وَإِن تُؤْمِنُوا وَتَتَّقُوا يُؤْتِكُمْ أُجُورَكُمْ وَلَا يَسْأَلْكُمْ أَمْوَالَكُمْ

he life of this world is but a play and a passing delight: but if you believe (in God) and are conscious of Him, He will give you your recompense.

And withal, He does not demand of you (to sacrifice in His cause all of) your possessions:

Surah Muhammad, 47:36-38
