Is the jealousy of Sayyidah Aisha, may Allah be pleased with her, despite her love for the Prophet, may Allah bless him and grant him peace, and his love for her, considered a sin?

Loving the Prophet (peace be upon him) is an individual obligation upon every Muslim. A person's faith is not complete unless Allah and His Messenger are more beloved to him than anything else, even more than himself, because loving them is a condition of faith. The religious texts indicate this, such as the Almighty's saying: "And of the people are some who take others besides Allah as equals [to Him]. They love them as they should love Allah. But those who believe are stronger in love for Allah," and the Prophet's saying (peace be upon him): "None of you will truly believe until I am more beloved to him than his father, his child, and all mankind." And in a narration by Ahmad: "and even himself." As for jealousy, some of it is praiseworthy, as narrated in the story of Sa'd ibn 'Ubadah and the jealousy of the Prophet (peace be upon him) and the jealousy of Allah.
