حُنَفَآءَ لِلَّهِ غَيْرَ مُشْرِكِينَ بِهِۦ ۚ وَمَن يُشْرِكْ بِٱللَّهِ فَكَأَنَّمَا خَرَّ مِنَ ٱلسَّمَآءِ فَتَخْطَفُهُ ٱلطَّيْرُ أَوْ تَهْوِى بِهِ ٱلرِّيحُ فِى مَكَانٍ سَحِيقٍ
Being true to God, without associating anything with Him. Whoever associates anything with God-it is as though he has fallen from the sky, and is snatched by the birds, or is swept away by the wind to a distant abyss. (Quran 22:31)
In this parable the sky or heaven means the original human nature. Man by nature is the servant of none else but The Magnificent Creator and inherently accepts the doctrine of Tauhid. That is why the one who follows the guidance of the Prophets becomes firm in these dictates of his nature and soars higher and higher. On the other hand, the one who rejects God or associates a partner with Him falls down from the heaven of his nature. Then he either becomes a victim of the devils and evil leaders similar to the birds of the parable, which snatch away the fallen man and misguide him on an erroneous path, or he becomes a slave of his lusts, passions, whims, etc., which have been likened to the wind in the parable. They lower him down from one wrong position to the other till he falls into the deepest abyss of degradation.
