I said to Imam Sādiq (a.s.), “Sometimes when we go to the Ziyārah of Ḥusain (a.s.), it is difficult to perform Ghusl because of the cold (climate) or for other reasons.” Imam (a.s.) replied, “So many merits will be registered for those who go to the Euphrates (River) and perform Ghusl in it before going to the Ziyārah of Ḥusain (a.s.), that they cannot be counted. And if they return anytime (in the future) to the place where they performed Ghusl, and (instead) perform Wuďū before going to the Ziyārah of Ḥusain (a.s.), the same (extent of) rewards will be registered for them.”
