Be mindful of Allah
احْفَظِ اللَّهَ يَحْفَظْكَ، احْفَظِ اللَّهَ تَجِدْهُ تُجَاهَكَ، إِذَا سَأَلْتَ فَاسْأَلِ اللَّهَ، وَإِذَا اسْتَعَنْتَ فَاسْتَعِنْ بِاللَّهِ
Ihfazi-llaha yahfazk, ihfazi-llaha tajid-hu tujahak. Idha sa'alta fa-s'ali-llah, wa idha-sta'anta fa-sta'in billah.
"Be mindful of Allah and He will protect you. Be mindful of Allah and you will find Him before you. When you ask, ask Allah. When you seek help, seek it from Allah."

A short reflection
The Prophet ﷺ speaking to a boy. Four lines you can keep on your tongue for life.
