Sura 12 Yusuf (Joseph), ayah 48

1. ثُمَّ يَأْتِي مِنْ بَعْدِ ذَٰلِكَ سَبْعٌ شِدَادٌ يَأْكُلْنَ مَا قَدَّمْتُمْ لَهُنَّ إِلَّا قَلِيلًا مِمَّا تُحْصِنُونَ

   Then will come after that seven difficult (years) which will consume what you saved for them, except a little from which you will store.

   12:48
