وَقَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: «إِنَّ آيَةَ اَلْمُؤْمِنِ إِذَا حَضَرَهُ اَلْمَوْتُ أَنْ يَبْيَضَّ وَجْهُهُ أَشَدَّ مِنْ بَيَاضِ لَوْنِهِ وَ يَرْشَحَ جَبِينُهُ وَ يَسِيلَ مِنْ عَيْنَيْهِ كَهَيْئَةِ اَلدُّمُوعِ فَيَكُونُ ذَلِكَ آيَةَ خُرُوجِ رُوحِهِ وَ إِنَّ اَلْكَافِرَ تَخْرُجُ رُوحُهُ سَلاًّ مِنْ شِدْقِهِ كَزَبَدِ اَلْبَعِيرِ كَمَا تَخْرُجُ نَفْسُ اَلْحِمَارِ.
Imam Muhammad ibn Ali Al-Baqir (a.s) said: "The sign of a believer when death approaches is that their face becomes whiter than its usual color, their forehead perspires, and tears flow from their eyes like drops. This is the sign of the departure of their soul. As for the disbeliever, their soul exits from their mouth forcefully, like the froth of a camel or the expiration of a donkey."
