Bismillaah:ُ

Nu'aim bin Hammar رضي الله عنه relates :

I heard the Messenger of Allaah صلى الله عليه وسلم say that Allaah عزوجل said:

"O son of Adam! Don't be prevented [deprived] from four Rak'ahs in the first part of your day, for [if you do so] I will take care of the latter
part “Son of Adam perform four Rak’at for Me in the beginning of the day; they will suffice you for the latter part of the day.”

Takhreej:

{ Imam Abu Dawud in his Sunnan#1291, Ahmad in his Musnad 2/235 and graded as Saheeh by Ibn Hibban, Abu Taahir and others }

Imam Al Mubarakfuri رحمه الله commented:

Rak’at for Me in the beginning of the day… Means: Salatul Duha, Salatul Ishraq, and Sunnat us Subh. These are the names for this prayer. At-Tebee رحمه الله said, “These four Rak’at are enough for your affairs and needs throughout the day [ to be made easy]. These four Rak’at repel from you whatever you dislike right through the day.

{ Tuhfatul Ahwadhi Sharh Jam'i At Tirmidhi }

Al Imam Ibn Al-Arabee رحمه الله commented:

"Salatul Duha is the prayer of the Prophets before Muhammad صلى الله عليه وسلم . Allaah says, 'Our Praises with him [ Dawud ] in the Ashi [after the midday until sunset] and Ishraq [sunrise till mid-day]“ { 38:18 }"

{ Aridatul Ahwadhi Sharh al Jam’i At-Tirmidhi }

*** And Allaahعزوجل knows best ***
