Ali Albarghouthi

An explanation of the second hadith in the Heart Therapy Series: The Messenger salla Allahi alayhi wa sallam said: (The qalb [heart] was given this name only because of its fluctuations. The heart is like a feather in the wilderness at a base of a tree that continues to be turned on its head by the wind) reported by Ahmad and al-Tabarani. Al-Iraqi declared it to be hasan, and al-Albani declared it as sahih.
