Respecting international treaties in what doesn’t violate the Islamic Sharia Law
When Muslims sign treaties with people of other faiths, that don’t violate the Islamic Sharia Law, then they are obligated to fulfill and highly regard them. To clarify this issue it is essential to explain certain things:
1. Muslims need to participate with other nations in human public welfare. Specifically, the welfare that espouse high ethical causes, general humanitarian principles, and reformation purposes that every single reasonable individual agrees upon espousing. Anything else that doesn’t violate Islamic Law is also included.
2. As demonstrated in the Sunna, the Prophet (pbuh) favoured the “Fodul” alliance, in which some of the tribes of the Quraish pledged alliance and agreed upon supporting and assisting every single oppressed Meccan citizens and others. Moreover, the Prophet (pbuh) was a witness of this alliance in the pre-Islamic period of ignorance, and he said after the revelation of the Quran: “I was a witness in the house of Abdullah ibn Jadan of an alliance that I would never revoke even for a sum of red camels (red camels were the most valuable things to Arabs at that time).” And if I was asked to be a witness in it again in Islam, I would accept.” – Narrated by Al-Bayhaqi
Abu Abbas Al-Qurtubi commented on this Hadith in Al-Mufhim by saying: “Due to what has been enforced in Islamic Law of assisting the oppressed by maintaining righteousness and upholding his rights without fail. Nevertheless, some of the pre-Islamic verdicts were revoked, yet the pact to maintain righteousness remained irrevocable. Even more, it was enforced as one of the Islamic Shariah verdicts, to whoever is capable.
3. Ibn Abbas said: Keeping these pacts is an obligation, for Allah Almighty said in the Quran “O you who believe fulfill your obligations”. Ibn Abbas and Mujahid said: “obligations are the pacts”, and Ibn Jarir said: “obligations refer to the pacts and pledges of alliance.”
