أحكام أهل الذمة
‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever kills a Mu‘āhad shall not smell the fragrance of Paradise, though its fragrance can be smelt at a distance of forty years (of traveling).''
عن عبد الله بن عمرو -رضي الله عنهما- عن النبي -صلى الله عليه وسلم- قال: «من قَتَلَ مُعَاهَدًا لم يَرَحْ رَائحَةَ الجنة، وإن رِيْحَهَا تُوجَدُ من مَسِيرَة أربعين عامًا».
شرح الحديث :
This Hadīth indicates that anyone who kills a Mu‘āhad will not be admitted to Paradise or even smell its fragrance, although its fragrance can be smelt at a distance of forty years of traveling. A Mu‘āhad is a non-Muslim who enters the lands of Muslims with a pact of security and protection, or a Dhimmi. The warning in the Hadīth proves that Islam is keen on preserving the lives of those who are given protection by Muslims, and that killing them is a major sin.
