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. (Using translation from Abū Dāʾūd 1289)
أَنَّ النَّبِيَّ ﷺ قَالَ إِنَّ اللهَ ﷻ يَقُولُ ابْنَ آدَمَ لَا تَعْجِزْنَّ مِنْ أَرْبَعِ رَكَعَاتٍ أَوَّلَ النَّهَارِ أَكْفِكَ آخِرَهُ
