Imam Husain b. Ali (a.s.) informed that the Messenger of Allah (s.a.w.a.) said: O Ali! You will be wronged after me. Woe unto those who fight against you, and blessed are those who fight for you.
O Ali! You speak my words and you speak with my tongue after me. Woe unto those who object to you, and blessed are those who accept your words.
O Ali! You are the master of this nation after me. You are the Imam of this nation and you are my caliph on my nation.
O Ali! Those who abandon you in this world have abandoned me on the Day of Judgement, and those who are with you in this world will be with me on the Day of Judgement.
O Ali! You were the first to believe in me and trust me. You were the first person who helped me with all of my affairs and you were the first person who fought against my enemies with me.
O Ali! You were the first person who prayed with me at a time when others were in the slumber of ignorance.
O Ali! You will be the first one who rises from his grave with me. You are the first person who will be resurrected with me, and you are the first person who will cross the Serat with me.
Allah has sworn to His own Glory that He will not allow any slave to cross the Serat except for those who carry a pass from you (that indicates) that they believe in your Wilayat and the Wilayat of the Imams from your sons.
O Ali! You will be the first person who comes to my Pool on the Day of Judgement.
You will distribute water to your friends from the Pool and you will keep your enemies away from the Pool.
O AliI You will be accompanying me when I stand at Maqaam al-Mahmood (the praised station) in front of Allah.
O Ali! You will intercede for those who love us and your intercession will be accepted.
O Ali! You will be the first one to enter Paradise carrying my flag. This flag of praise has seventy sides, and each side is wider than the sun and the moon.
O Ali! You are the owner of the tree of Tooba in Paradise. Its roots are in your house, and its branches are in the houses of your Shia and of those who love you. 283
