Messenger of Allah narrated that Allah, Blessed and Most High said: "Son of Adam: Perform four Rak'ah for Me in the beginning of the day it will suffice you for the latter part of it."

عَنْ رَسُولِ اللَّهِ ﷺ عَنِ اللَّهِ ﷻ أَنَّهُ قَالَ ابْنَ آدَمَ ارْكَعْ لِي مِنْ أَوَّلِ النَّهَارِ أَرْبَعَ رَكَعَاتٍ أَكْفِكَ آخِرَهُ
