Pray humbly with respect and gratitude towards Allah in times of need.

This hadith tells us about the Prophet Muhammad's practice of praying for rain while wearing a black cloak, known as a khamisah. It is believed that this was done to show humility and reverence to Allah, as well as to demonstrate the importance of prayer in times of need. The Prophet Muhammad's example serves as an important reminder that we should always turn to Allah in times of difficulty and ask Him for help. We should also remember that prayer is not only about asking God for something, but also about expressing gratitude and appreciation for His blessings. Furthermore, this hadith teaches us the importance of humility when approaching Allah; by wearing a simple black cloak instead of his usual clothing, the Prophet showed his respect and submission to God's will.
