عن عمر بن الخطاب وابنه عبد الله وأبي هريرة رضي الله عنهم مرفوعاً: «أُمِرْتُ أن أقاتل الناس حتى يشهدوا أن لا إله إلا الله وأن محمدًا رسول الله، ويُقيموا الصلاة، ويُؤتوا الزكاة، فإذا فعلوا ذلك عصموا مني دماءَهم وأموالَهم إلا بحق الإسلام وحسابُهم على الله تعالى ».
[صحيح] - [متفق عليها. حديث عبد الله بن عمر بن الخطاب -رضي الله عنه-: رواه البخاري (1/ 14 رقم25)، ومسلم (1/ 53 رقم22). حديث عمر بن الخطاب -رضي الله عنه-: رواه البخاري (2/ 105 رقم1399) (9/ 15 رقم6924) (9/ 93 رقم7284)، ومسلم (1/ 51 رقم20). حديث أبي هريرة -رضي الله عنه-: رواه البخاري (4/ 48 رقم2946)، ومسلم (1/ 52 رقم21)]
‘Umar ibn al-Khattāb, his son ‘Abdullāh, and Abu Hurayrah (may Allah be pleased with them) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "I have been commanded to fight against the people until they testify that there is no god but Allah and that Muhammad is the Messenger of Allah, and until they establish the prayer and pay the Zakah. If they do so, their blood and property are guaranteed my protection, unless (they commit acts that are punishable) in accordance with Islam, and their reckoning will be with Allah, the Almighty."
Sahih/Authentic. - [Al-Bukhari and Muslim with all its versions]
Allah, the Almighty, ordered fighting the polytheists (who associate others with Him in worship) until they testified that there is no god but Allah alone, without partners and that Muhammad (may Allah's peace and blessings be upon him) is the Messenger of Allah, and that they perform the acts of worship that this testimony entails; the five daily obligatory prayers and Zakah when it becomes due. If they fulfill these pillars (of Islam) along with what else Allah has made obligatory for them, their lives and property become inviolable by virtue of their reversion to Islam. Excluded from such inviolability are actions that entail retribution or a prescribed punishment under the Shariah. Whoever sincerely complies with what he is commanded to do is a believer, and whoever complies out of precautionary dissimulation and fear for his life and property is a hypocrite. Allah knows his true intention and He will hold him accountable for it.
