حَدَّثَنَا حَامِدُ بْنُ عُمَرَ، عَنْ حَمَّادِ بْنِ زَيْدٍ، عَنْ لَيْثٍ، عَنْ مُجَاهِدٍ قَالَ: كَانَ يَكْرَهُ أَنْ يُحِدَّ الرَّجُلُ النَّظَرَ إِلَى أَخِيهِ، أَوْ يُتْبِعَهُ بَصَرَهُ إِذَا قَامَ مِنْ عِنْدِهِ، أَوْ يَسْأَلَهُ: مِنْ أَيْنَ جِئْتَ، وَأَيْنَ تَذْهَبُ؟
It is narrated from Mujahid (may Allah have mercy on him) that he disliked looking at a Muslim brother with sharp eyes. Similarly, when he got up to leave, he disliked watching him from behind (to see where he was going). He also disliked asking, "Where have you come from and where are you going?"
