Respond positively and promptly when called upon by a messenger

In this hadith, the Prophet Muhammad is conveying an important message about responding positively and promptly when called upon by a messenger. He uses the example of Joseph, who was imprisoned for many years before being released by Pharaoh's court. Despite his lengthy imprisonment, Joseph responded immediately when Pharaoh's court summoned him. The Prophet Muhammad is thus emphasizing that we should always be ready and willing to answer any call from a messenger or authority figure without hesitation or delay. This hadith also teaches us that we should never give up hope in difficult times; just like Joseph did not lose faith despite his long imprisonment, we too should remain hopeful and trust in Allah’s plan for us no matter what our circumstances may be.
