Use a siwk before praying

This hadith emphasizes the importance of cleanliness before prayer. It is narrated that Zaid bin Khalid Al-Juhani heard Allah's Messenger saying that if it were not difficult on his nation, he would have ordered them to use a siwak for each prayer and to delay their Isha prayer until the third part of the night. A siwak is a small twig used as a toothbrush which was commonly used in those days. It is also known as miswak or datun in some parts of the world. By using this tool, one can ensure that their mouth and teeth are clean before they pray, thus fulfilling an important part of Islamic hygiene practices. Additionally, delaying Isha prayers until late at night allows one to get enough rest and be more alert during prayers. This hadith serves as an important reminder for Muslims to take care when preparing for their daily prayers by ensuring they are clean and well rested beforehand.
