Where it sits. Cognitive offloading and externalizing
Islamic evidence
Lord, ease my task for me (Quran 20:26). Arranging your surroundings to carry the load is a way of easing your own task.
“and ease my task for me”
Qur'an 20:26
Psychological evidence
Letting the environment hold your reminders, visible cues placed where you will act, reliably outperforms trying to remember, especially for a mind that loses track of intentions.
Risko, E. F. and Gilbert, S. J. (2016). Trends in Cognitive Sciences · doi
Offloading information to the environment, such as notes and reminders, reduces cognitive load and improves task performance.

Why it works. Placing cues in the environment offloads remembering onto your surroundings instead of your memory.
