Dua:

Supplication, or Dua in Arabic, is a form of worship in Islam that involves asking Allah for His help, guidance, and forgiveness. It is a way for Muslims to connect with Allah and seek His blessings in all aspects of life. Prophet Muhammad, peace be upon him, provides guidance on how to make supplications that are pleasing to Allah. He encouraged Muslims to make dua frequently and taught them the proper etiquettes of making supplications, such as starting with praising Allah, sending blessings upon the Prophet, and being sincere in their intentions. Prophet Muhammad s.a.w also taught his followers to make specific supplications for different occasions, such as before eating, sleeping, or traveling. The Sunnah of Prophet Muhammad thus emphasizes the importance of making supplication and provides guidance on how to do it in a way that is pleasing to Allah 

Sunnah:

The Sunnah of Prophet Muhammad refers to his actions, teachings, and way of life that he showed to his followers as an example. It includes everything from the way he prayed, how he dressed, his interactions with people, his dietary habits, and much more. The Sunnah is an important aspect of Islamic tradition as it provides guidance and inspiration for Muslims to follow in their daily lives. By following the Sunnah, Muslims can learn how to live a life that is pleasing to Allah and how to behave in a manner that is respectful and kind towards others. In essence, the Sunnah of Prophet Muhammad serves as a guide for Muslims on how to achieve success in this world and in the Hereafter.
