An offender gets embroiled in various diseases
The life of the martyrs is well established through the Holy Quran and Hadith. After martyrdom, they are seated on high stations of closeness to Allah Most High. Thus, they have more powers than they had in their previous existence. After the martyrdom of Imam Hussain (May Allah be well pleased with him), many miracles were expressed.
Imam Tabarani writes in Mo’jam Kabeer:
Translation: Hadhrat Jareer narrates on the authority of Hadhrat A’amash (May Allah be well pleased with him) that a wretch urinated and defecated on the blessed grave of Imam Hussain (May Allah be well pleased with him). That very instant, his family members were afflicted by various diseases like paralysis, lunacy, leprosy and various other diseases. They went bankrupt and became dirt poor. (Mo’jam Kabeer Tabarani, Hadith No. 2791)
After relating this Tradition, ‘Allama Nooruddin Haithami (May Allah shower His Mercy on him) writes: Those who relate this Hadith are reliable. (Majma’ ‘Uz Zawaaid, Vol. 9, Pg. No. 197)
This shows Allah Most High inflicted various deadly diseases on the family of the person who disrespected the blessed grave of Imam Hussain (May Allah be well pleased with him).
