Narrated Muhammed bin Jafar: On the authority of Awf:
حَدَّثَنَا ابْنُ بَشَّارٍ، قَالَ: قَالَ مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ عَوْفٌ: الْعِيَافَةُ زَجْرُ الطَّيْرِ وَالطَّرْقُ الْخَطُّ يُخَطُّ فِي الْأَرْضِ .
'Iyafah means to makes the birds fly by threatening them. Tarq means lines drawn on the earth.
