Perform wudu/tayamumm prior to engaging in salat/prayer

This hadith is about the importance of performing ablution and tayammum before prayer. It was narrated by Abu Qais that Amr b. al-'As was in a battle when he washed his armpits and other joints where dirt was found, then performed ablution like that for prayer before leading them in prayer. The tradition has also been narrated by Hassan b.'Atiyyah on the authority of al-Awza'i with an additional mention of tayamumm being performed as well. This hadith highlights the importance of cleanliness and purity when engaging in acts of worship such as salat or prayer to Allah SWT which is one of the five pillars of Islam for Muslims to practice daily or weekly depending on their circumstances or location they are at during that time period .
