Yusuf - 12:48

ثُمَّ يَأْتِي مِن بَعْدِ ذَلِكَ سَبْعٌ شِدَادٌ يَأْكُلْنَ مَا قَدَّمْتُمْ لَهُنَّ إِلاَّ قَلِيلاً مِّمَّا تُحْصِنُونَ
[12:48]
Then there shall come after that seven years of hardship which shall eat away all that you have beforehand laid up in store for them, except a little of what you shall have preserved:
"Then will come after that (period) seven dreadful (years), which will devour what ye shall have laid by in advance for them,- (all) except a little which ye shall have (specially) guarded.
Then after that will come seven hard years which will devour all that ye have prepared for them, save a little of that which ye have stored.
