This hadith is about the Prophet Muhammad's practice of pronouncing a supplication called "Talbiya" when he returned from the gathering of people at a place called "Muzdalifa". Abdullah ibn Mas'ud reminded people that this was part of the tradition or "Sunnah" that was revealed to him in Surah al-Baqara. This hadith teaches us to follow in the footsteps of Prophet Muhammad and remember his teachings even when we are performing religious rituals such as Hajj, which is an Islamic pilgrimage to Mecca. It also reminds us to be mindful and aware of our actions so that we can stay true to our faith and practice it correctly according to its teachings.
