عن طارق بن أشيم الأشجعي مرفوعاً: "من قال لا إله إلا الله، وكَفَرَ بما يُعْبَدُ من دون الله حَرُمَ مالُه ودمُه وحِسابُه على الله".
[صحيح] - [رواه مسلم]
المزيــد ...
Tāriq ibn Ashīm al-Ashja‘i (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "c2">“Whoever says, 'there is no god but Allah' and disbelieves in everything worshiped besides Allah, his property and blood becomes inviolable, and his reckoning will be with Allah.”
Sahih/Authentic. - [Muslim]
In this Hadīth the Prophet (may Allah's peace and blessings be upon him) clarifies that when two requirements are met, it becomes forbidden to kill someone and take his wealth : 1. saying: 'there is no god but Allah'. 2. Disbelieving in everything worshiped besides Allah. If these two conditions are fulfilled, it becomes incumbent to refrain from harming such a person, based on his apparent words, and to leave his inward faith to Allah, the Almighty. This applies as long as he does not commit a sin that makes it lawful to spill his blood, e.g. apostasy; to take his wealth, e.g. Zakah evasion; or to damage his reputation, e.g. procrastination in the repayment of debt.
