وَالْبَلَدُ الطَّيِّبُ يَخْرُجُ نَبَاتُهُ بِإِذْنِ رَبِّهِ وَالَّذِي خَبُثَ لاَ يَخْرُجُ إِلاَّ نَكِدًا كَذَلِكَ نُصَرِّفُ الآيَاتِ لِقَوْمٍ يَشْكُرُونَ
And the good land - its vegetation emerges by permission of its Lord; but that which is bad - nothing emerges except sparsely, with difficulty. Thus do We diversify the signs for a people who are grateful.
