Mujahid said, "It is disliked for a man to look sharply at his brother or to follow him with his glance when he leaves or to ask him, 'Where have you come from and where are you going?'"  

أَنْ يُحِدَّ الرَّجُلُ النَّظَرَ إِلَى أَخِيهِ أَوْ يُتْبِعَهُ بَصَرَهُ إِذَا قَامَ مِنْ عِنْدِهِ أَوْ يَسْأَلَهُ مِنْ أَيْنَ جِئْتَ وَأَيْنَ تَذْهَبُ؟  

Malik ibn Zubayd said, "We passed by Abu Dharr at ar-Rabadha. He said, 'Where have you come from?' We said, 'Makka - or from the Ancient House.' He said, 'Is this what you have done?' We said, 'Yes.' He said, 'And was there commerce or selling with it?' 'No,' he replied. He said, 'Then resume your actions anew.'"
