فَلِذَٰلِكَ فَٱدْعُ ۖ وَٱسْتَقِمْ كَمَآ أُمِرْتَ ۖ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ ۖ وَقُلْ ءَامَنتُ بِمَآ أَنزَلَ ٱللَّهُ مِن كِتَٰبٍۢ ۖ وَأُمِرْتُ لِأَعْدِلَ بَيْنَكُمُ ۖ ٱللَّهُ رَبُّنَا وَرَبُّكُمْ ۖ لَنَآ أَعْمَٰلُنَا وَلَكُمْ أَعْمَٰلُكُمْ ۖ لَا حُجَّةَ بَيْنَنَا وَبَيْنَكُمُ ۖ ٱللَّهُ يَجْمَعُ بَيْنَنَا ۖ وَإِلَيْهِ ٱلْمَصِيرُ
Unto this, then, summon (O Muhammad). And be thou upright as thou art commanded, and follow not their lusts, but say: I believe in whatever scripture Allah hath sent down, and I am commanded to be just among you. Allah is our Lord and your Lord. Unto us our works and unto you your works; no argument between us and you. Allah will bring us together, and unto Him is the journeying.

Sahih al-Bukhari
Prayer at Night (Tahajjud)
Chapter: To offer Salat-ud-Duha when not traveling
Narrated Anas bin Sirin:
I heard Anas bin Malik al-Ansari saying, "An Ansari man, who was very fat, said to the Prophet, 'I am unable to present myself for the prayer with you.' He prepared a meal for the Prophet (ﷺ) and invited him to his house. He washed one side of a mat with water and the Prophet (ﷺ) offered two Rakat on it." So and so, the son of so and so, the son of Al-Jarud asked Anas, "Did the Prophet (ﷺ) use to offer the Duha prayer?" Anas replied, "I never saw him praying (the Duha prayer) except on that day."
