The nutrition for a whole day...
Is not impossible.
Can be consumed like the days of the blessed prophet.
7 dates can be a meal for the whole day.
Along with glasses of milk and water for thirst.
Every nutrition is in the dates in 7 of them.
Consume for all the valuble nutrients in the whole day.
Energy and extra for your work and more Time and Devotion to your Lord.
Your mind more focused your concentration upon the hills so you can pray with more ease and less pain hopefully.
