 For those who ask, why do the Shi'a visit the shrine of Imam Al-Hussain, alaihi salam? For the lovers of Imam Al-Hussain, alaihi salam, nothing makes them happier than to be in his holy shrine, which is why every year millions of people flock towards the holy city of Karbala, especially on the days of Ashura and Arba'een. It was the Ahl al-Bayt, alaihi salam, themselves, alongside the righteous companion of the Prophet Muhammad, sallallahu alayhi wa alayhi, Jabir ibn Abdullah al-Ansari, were the first to perform the pilgrimage of the Imam on the 20th of Safar, exactly 40 days since the massacre of Karbala, hence why it is referred to as Arba'een. In the days leading up to Arba'een, it is not uncommon to see people walking from Najaf to Karbala, emulating how the Ahl al-Bayt, alaihi salam, walked to the Imam after their ordeals in Damascus. In fact, some people even walk as far as from Basra in the south of Iraq and even from the Iranian border just to get to Karbala. The rewards and benefits of visiting the shrine of Imam al-Hussain alaihi salam in Karbala are so numerous that whole books have been written on this topic. Amongst these narrations, there is a dua'a that was recited by Imam al-Sadiq alaihi salam. O Allah, forgive me and my brothers and sisters, those who go on Ziyarah to my father, Hussain alaihi salam, spending their wealth to travel, seeking to please us and hoping for the reward you have prepared for them. They go on Ziyarah to make your messenger, sallallahu alaihu alaihi happy, and our enemies have criticised them for going. So have mercy on those faces which have been burnt by the sun, and have mercy on those cheeks that have been rubbed themselves on the grave of Imam al-Hussain alaihi salam. Have mercy on those eyes that have shed tears for us in sympathy, and have mercy on those hearts which have become restless and anguished for us, and have mercy on those screams for us. O Allah, I entrust them to you until the day of great thirst, when you will quench the thirst with the pool of kufr. May Allah SWT include us amongst the visitors of Imam al-Hussain alaihi salam, and those for whom the Holy Prophet, Lady Fatima, and the Imam of Zahreel Bayt alaihi salam pray for.
