وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلْجَنَازَةِ يُخْرَجُ مَعَهَا بِالنَّارِ فَقَالَ «إِنَّ اِبْنَةَ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ أُخْرِجَ بِهَا لَيْلاً وَ مَعَهَا مَصَابِيحُ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked about a funeral procession in which fire (torches or lamps) is carried. Imam عليه السلام replied: "The daughter of the Messenger of Allah صلى الله عليه وعلى آله وسلم was taken out at night, and lamps accompanied her."
