قَالَ تَزْرَعُونَ سَبْعَ سِنِينَ دَأَبًا فَمَا حَصَدتُّمْ فَذَرُوهُ فِى سُنۢبُلِهِۦٓ إِلَّا قَلِيلًا مِّمَّا تَأْكُلُونَ

[Joseph] said, "You will plant for seven years consecutively; and what you harvest leave in its spikes, except a little from which you will eat.

ثُمَّ يَأْتِى مِنۢ بَعْدِ ذَٰلِكَ سَبْعٌ شِدَادٌ يَأْكُلْنَ مَا قَدَّمْتُمْ لَهُنَّ إِلَّا قَلِيلًا مِّمَّا تُحْصِنُونَ

Then will come after that seven difficult [years] which will consume what you advanced [i.e., saved] for them, except a little from which you will store.
