Going into something new
Mūsā ﷺ was told to say this. So was the Prophet ﷺ, at the hijrah.
وَقُل رَّبِّ أَدْخِلْنِى مُدْخَلَ صِدْقٍ وَأَخْرِجْنِى مُخْرَجَ صِدْقٍ وَٱجْعَل لِّى مِن لَّدُنكَ سُلْطَـٰنًا نَّصِيرًا
Rabbi adkhilnī mudkhala ṣidqin wa akhrijnī mukhraja ṣidqin wa-jʿal lī min ladunka sulṭānan naṣīrā.
And say, "My Lord, cause me to enter a sound entrance1 and to exit a sound exit2 and grant me from Yourself a supporting authority."
