aisha may allah be pleased with her used to describe to the one who suffers from dizziness that he should eat seven dates in the morning on an empty stomach for seven days. whenever the messenger of allah had a headache he would cover his head with henna and he would suffer from a headache from the revelation when it came down to him.
وكانت عائشة رضي الله عنها تنعت لصاحب الدوام أن يأكل سبع تمرات ضحوة لكل يوم على الريق سبعة أيام. وكان رسول الله إذا أصابه الصداع غلف رأسه بالحناء، وكان يصدع من الوحي إذا نزل عليه.
