Sunan an-Nasā'ī 1163
لاَ إِلَهَ إِلاَّ اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ وَلْيَتَخَيَّرْ أَحَدُكُمْ مِنَ الدُّعَاءِ أَعْجَبَهُ إِلَيْهِ فَلْيَدْعُ اللَّهَ عَزَّ وَجَلَّ
lā ilaha illā-Llāh wa-ashhadu anna muḥammadan ʿabduhu warasūluhu walyatakhayyar aḥadukum mina ad-duʿāʾi aʿjabah ilayhi falyadʿu-Llāh ʿazza wajalla

The full narration
It was narrated that 'Abdullah said:"We used not to know what we should say in each rak'ah apart from glorifying, magnifying and praising our Lord. But Muhammad (ﷺ) taught us everything about what is good. He said: "When you sit following every two rak'ahs, then say: At-tahiyyatu lillahi was-salawatu wat-tayyibat, as-salamu 'alaika ayyuhan-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu 'alaina wa 'ala 'ibad illahis-salihin, ashahdu an la illaha ill-Allah wa ashhadu anna Muhammadan 'abduhu wa rasuluhu (Allah compliments, prayers and pure words are due to Allah. Peace be upon you, O Prophet, and the mercy of Allah (SWT) and his blessings. Peace be upon us and upon the righteous slaves of Allah (SWT). I bear witness that none has the right to be worshipped except Allah and I bear witness that Muhammad is His slave and Messenger), then choose any supplication that you like and call upon Allah the Mighty and Sublime with it
