Hadith.5175 - Al-Hasan ibn Mahbub narrated from Ali ibn Ri'ab from Abu Basir from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, who said: "Indeed, Allah سبحانه وتعالى, Blessed and Exalted, has ruled differently regarding your blood than He سبحانه وتعالى has regarding your wealth. In matters of wealth, the ruling is that the burden of proof is upon the claimant, and the oath is upon the one against whom the claim is made. However, in matters of blood, the ruling is that the oath is upon the claimant, and the proof is upon the one against whom the claim is made, so that the blood of a Muslim is not unjustly nullified."
