The nearest a slave to his Lord is while he is prostrating, so increase supplication

The Prophet (may Allah's peace and blessings be upon him) pointed out that the closer a servant comes to his Lord is when he is prostrating, for he puts the highest and noblest part of his body on the ground in submission and humility to Allah Almighty. The Prophet (may Allah's peace and blessings be upon him) ordered us to increase supplication while prostrating. Thus, we become submissive to Allah both by words and action.
