…consider the pervading power of those drops of the blood of Husayn [1] which besprinkled the earth. What ascendancy and influence hath the dust itself, through the sacredness and potency of that blood, exercised over the bodies and souls of men! So much so, that he who sought deliverance from his ills, was healed by touching the dust of that holy ground, and whosoever, wishing to protect his property, treasured with absolute faith and understanding, a little of that holy earth within his house, safeguarded all his possessions. 
- Baha’u’llah  (‘The Kitab-i-Iqan’)
[1] Iman Husayn Who was martyred
