Hadith qudsi Sunan Abu Dawud 1289
I heard the Messenger of Allah (ﷺ) say: Allah, the Exalted, says: Son of Adam, do not be helpless in performing four rak'ahs for Me at the beginning of the day: I will supply what you need till the end of it.
يَقُولُ اللَّهُ عَزَّ وَجَلَّ يَا ابْنَ آدَمَ لاَ تُعْجِزْنِي مِنْ أَرْبَعِ رَكَعَاتٍ فِي أَوَّلِ نَهَارِكَ أَكْفِكَ آخِرَهُ "
