When you start something, eating,drinking,writing, reading something start saying ‘Bismillah’ -

بِسْمِ اللَّهِ

Bismillaah

In the Name of Allah. Narrated 'Umar ibn Abi Salamah (RA): I was a boy under the care of the Messenger of Allah (ﷺ). While eating, I would put my hands in different places of the pot. Then the Messenger of Allah (ﷺ) said to me, “This boy! Say Bismillah, eat, and the next part of your right to eat! "After the meal, I'm going to follow the instructions.
