I heard the Messenger of Allah ﷺ say: Augury from the flight of birds, taking evil omens and the practice of pressomancy pertain to divination. Tarq: It is used in the sense of divination in which women threw stones. 'Iyafah: It means geomancy by drawing lines.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْعِيَافَةُ وَالطِّيَرَةُ وَالطَّرْقُ مِنَ الْجِبْتِ الطَّرْقُ الزَّجْرُ وَالْعِيَافَةُ الْخَطُّ  

On the authority of 'Awf: 'Iyafah means to makes the birds fly by threatening them. Tarq means lines drawn on the earth.  

عَوْفٌ الْعِيَافَةُ زَجْرُ الطَّيْرِ وَالطَّرْقُ الْخَطُّ يُخَطُّ فِي الأَرْضِ  

I said: Messenger of Allah! among us there are men who practice divination by drawing lines. He said: There was a Prophet who drew lines, so if anyone does it as he drew lines, that is right.  

قُلْتُ يَا رَسُولَ اللَّهِ وَمِنَّا رِجَالٌ يَخُطُّونَ قَالَ كَانَ نَبِيٌّ مِنَ الأَنْبِيَاءِ يَخُطُّ فَمَنْ وَافَقَ خَطَّهُ فَذَاكَ
