Hadith.5379 - Al-Hasan ibn Ali ibn Faddal narrated from Zharif ibn Nasih, from Aban ibn Uthman, from Abu Basir, who narrated from Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) regarding a man who intentionally killed another man and then fled, and he could not be captured until he died.
Imam (as) said
"If he had wealth, the blood money is taken from it. If he had no wealth, it is taken from his closest relatives, and then from those next closest to him."
