The Messenger of Allah (ﷺ) commenced the prayer when he got up at night. Here is a part of it -

وَاهْدِنِيْ لِأَحْسَنِ الْأَخْلَاقِ لَا يَهْدِيْ لِأَحْسَنِهَا إِلَّا أَنْتَ وَاصْرِفْ عَنِّي سَيِّئَهَا لَا يَصْرِفُ عَنِّي سَيِّئَهَا إِلَّا أَنْتَ

Wahdini li ahsanil-akhlaaqi, la yahdi li ahsanihaa illa anta wasrif anni sayyi'ahaa laa yasrifu anni sayyi'ahaa illa anta

Guide me to the best of manners for none can guide to the best of them but You. Protect me from bad manners for none can protect against them but You.
