الجبار
الجَبْرُ في اللغة عكسُ الكسرِ، وهو التسويةُ، والإجبار القهر،...
Ibn ‘Umar (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: “A Muslim person must listen and obey concerning what he likes and hates, unless he is ordered to commit a sin. If he is ordered to commit a sin, then he should neither listen nor obey.”
شرح الحديث :
According to this Hadīth, it is mandatory to listen to and obey the ruler, whether or not one likes his commands. Only if one is ordered to commit a sin, he is not under obligation to listen and obey concerning this specific order.
