Narrated my father, may Allah have mercy on his soul, from Sa'd Ibn Abdullah from Ya'qub Ibn Yazid from Mohammad Ibn Abi Umayr from Muawiyah Ibn Wahab, who said: once I entered upon Abi Abdullah (عليه السلام) and saw him busy in worship on the prayer-mat. I waited till the Imam (عليه السلام) concluded his prayers. Then he started supplicating to Lord, “O Lord! You have granted us special ranks and gave us permission to intercede. You gave us the knowledge of prophets and made their inheritors. You ended the time of past communities when we arrived. You made us successors of the Holy Prophet (صلی الله وعليه وآله) and gave us the knowledge of past and future and directed the hearts of people towards us.
Forgive my brothers and the visitors of Imam Husain (عليه السلام) and forgive those who spend their wealth and leave their homeland and come for the Ziyarat of Imam Husain (عليه السلام). They have come to seek goodness from us, reward from You, to meet us, to make Your Messenger (صلی الله وعليه وآله) glad. They have come to obey our orders while they wanted to make Your Messenger (صلی الله وعليه وآله) happy by doing this.
O Allah! Grant them our pleasure for this deed. Protect them day and night; safeguard their family and children whom they have left behind in their homeland. Keep them safe of every oppressor, enemy – weak or strong, mischief of Jinn or men. Grant them much more than they expect from You. When they were coming towards us leaving their homeland, family and children behind, our enemies were teasing them.
O Allah! Shower Your mercy on those faces whose color changed during the journey due to the hot sun. Shower mercy on those cheeks, which rubbed against the grave of Imam Husain (عليه السلام). Shower mercy on those eyes, which are crying on us. Shower mercy on those hearts, which are sad due to our calamities. Shower mercy on those loud wails, which came out upon hearing our troubles.
O Allah! I hand over their bodies and souls to You so that You satisfy them at the cistern of Kauthar when people would be thirsty.” Imam (عليه السلام) prayed this again and again while prostrating.
When he concluded his supplications and stood up from the prayer-mat, the narrator said, “If the supplication, which you were saying now is said for a person who does not even recognize Allah then too I doubt if the fire of Hell would touch him. By Allah I wished that I had visited his grave and had not visited Hajj.”
Imam (عليه السلام) said, “You stay near the pure grave of Imam (عليه السلام). What stops you from doing his Ziyarat? O Muawiyah Ibne Wahab! Do not miss the Ziyarat of Imam (عليه السلام).”
Muawiyah said, “May I be sacrificed on you, I never knew the excellence of the Ziyarat of Imam (عليه السلام) was such.”
Imam said, “O Muawiyah! The number of creatures in the heaven praying for the visitors of Imam Husain (عليه السلام) is much more than that of those praying on this earth.
O Muawiyah! Do not miss the Ziyarat of Imam Husain (عليه السلام) out of any fear for one who leaves Ziyarat out of any fear would face such a surprise and shame that he would wish that he should have performed Ziyarat all the time and would wish to have been buried over there.
Don’t you like that the Almighty Allah includes you among those for whom the Holy Prophet (صلی الله وعليه وآله) prays?
Don’t you like to be among those with whom angels will shake hands on the Day of Judgment?
Don’t you like to be among those who come on the Day of Judgment with no sins to their names?
Don’t you like to be among those with whom the Holy Prophet (صلی الله وعليه وآله) will shake hands on the Day of Judgment?”

When one group comes down, the other group goes up.”
