وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، عَنِ الْعَلاَءِ بْنِ، يَعْقُوبَ قَالَ أَخْبَرَنِي أَبِي أَنَّهُ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَلَمْ تَرَوُا الإِنْسَانَ إِذَا مَاتَ شَخَصَ بَصَرُهُ ‏"‏ ‏.‏ قَالُوا بَلَى ‏.‏ قَالَ ‏"‏ فَذَلِكَ حِينَ يَتْبَعُ بَصَرُهُ نَفْسَهُ ‏"‏ ‏.‏

Abu Huraira reported Allah's Messenger (PBUH) as saying: Did you not see when the man died and his eyes were fixedly open? He (Abu Huraira) said: Yes. He (the Holy Prophet) said: It is due to the fact that when (the soul leaves the body) his eyesight follows the soul. Translation Not Available
