Have a proper posture when praying; Keep your hands together; Show respect for Allah through your actions during prayer; Be humble while praying.

This hadith is about the Prophet Muhammad's prayer posture. It was narrated by three people - Alqamah bin Wa'il, Musa bin Umair Al-Anbari and Qais bin Sulaim Al-Anbari - that they saw the Prophet standing in prayer while holding his left hand with his right. This shows us that it is important to have a proper posture when we are praying and to be mindful of our body language during prayer. We should also strive to keep our hands together as this helps us focus on our prayers and stay present in the moment. Additionally, this hadith teaches us about humility and respect for Allah as we show Him reverence through our actions during prayer.
