Imam Sadiq (a.s.) informed Dawood Riqqi – ‘… when a person remembers Imam Husain (a.s.) while drinking water, Allah writes for him 100,000 virtues, forgives 100,000 sins and elevates his position by 100,000 degrees and it is as if that person has released 100,000 slaves. Allah will raise him on the Day of Resurrection with a contented heart.’
