وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «مَا مِنْ أَحَدٍ يَحْضُرُهُ اَلْمَوْتُ إِلاَّ وَكَّلَ بِهِ إِبْلِيسُ مِنْ شَيَاطِينِهِ مَنْ يَأْمُرُهُ بِالْكُفْرِ وَ يُشَكِّكُهُ فِي دِينِهِ حَتَّى يَخْرُجَ نَفْسُهُ فَإِذَا حَضَرْتُمْ مَوْتَاكُمْ فَلَقِّنُوهُمْ شَهَادَةَ أَنْ لاَ إِلَهَ إِلاَّ اَللَّهُ وَ أَنَّ مُحَمَّداً رَسُولُ اَللَّهِ حَتَّى يَمُوتُوا.
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "There is no one who is faced with death except that Iblis (Satan) sends some of his devils to entice him toward disbelief and to cause him to doubt his faith until his soul departs. Therefore, when you are present with your dying ones, instruct them to bear witness that there is no god but Allah (swt) and that Muhammad is the Messenger of Allah (saws) until they pass away."
