Have faith and trust in Allah while making duas or supplications; Never lose hope; Be earnest while praying/supplicating; Put your trust in Allah's mercy and power .

This hadith is about the Prophet Muhammad's (PBUH) supplications for rain. He raised his hands in prayer and supplication to Allah until the whiteness of his armpits was visible. This shows us how earnestly he prayed and how much faith he had that Allah would answer his prayers. It also teaches us that we should never give up hope when praying to Allah and that we should always have faith that our prayers will be answered. We can learn from this hadith to always put our trust in Allah and never lose hope when making duas or supplications to Him.
