Narrated Ibn Mas'ud (RA):

Allah's Messenger (ﷺ) said: "One of the best deeds is to offer Salat (prayer) in its early time." [Reported by at-Tirmidhi and al-Hakim who (both) graded it Sahih].

وَعَنْ اِبْنِ مَسْعُودٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ أَفْضَلُ اَلْأَعْمَالِ اَلصَّلَاةُ فِي أَوَّلِ وَقْتِهَا } رَوَاهُ اَلتِّرْمِذِيُّ, وَالْحَاكِمُ.‏ وَصَحَّحَاهُ [1]‏ .‏
