قَالَ أَبُو عَبْدِ اللَّهِ ع مَا أَتَى مِنْ ثَلَاثِينَ فَرْسَخاً فَبِالْهِدَايَةِ وَ مَا كَانَ أَكْثَرَ مِنْ ذَلِكَ فَبِالْأُكُلِ.
“Abu ‘Abd Allah (a.s.), has said, ‘That (bird) which comes back from a distance of thirty farsakh is because of guidance and from a distance of more than this is because of food.’”
