عن النبى (ص) قال: ... و هى اطهر بقاع الارض واعظمها حرمة و إنها لمن بطحاء الجنة.
The Prophet of Islam (PBUH) also says in a long hadith: Karbala is the purest shrine on earth and the greatest shrine in terms of respect. Indeed, Karbala is one of the gardens of Paradise.
قال رسول الله صلى الله علیه و آله: یقبر ابنى بأرض یقال لها کربلا هى البقعة التى کانت فیها قبة الاسلام نجا الله التى علیها المؤمنین الذین امنوا مع نوح فى الطوفان.
The Prophet of God (PBUH) said: My son Hussain will be buried in a land called Karbala, a distinguished land that has always been the dome of Islam, just as God saved the believing companions of Prophet Noah from the flood there.
