The knowledgeable scholar Abu Ali Hasan bin Abi Jaafar Al-Tousi, narrated from his blessed father Abu Jaafar Mohammad bin Hasan Al- Tousi, from the scholar Abu Abdillah Mohammad bin Mohammad bin No’man, from Abul Qasem Jaaafar bin Mohammad, from his father, from Saad bin Abdullah, from Ahmad bin Mohammad bin Isa, from Safwan bin Yahya, from Yaqoub bin Shoaib, from Saleh bin Maitham Al-Tammar, from Maitham Al-Tammar, who said:
We spent one night with the Commander of the Believers, Ali bin Abi Taleb, and he said:
Every slave of Allah who believes in Him finds our love in his heart, and every slave whom Allah resents (because of their disbelief) hates us. We are happy for those who love us, and we know those who hate us.
The days of those who love us are passing while waiting and expecting the Mercy of Allah. But the days of those who hate us are passing while they are building their houses on the brink of Hell. And it is as if the houses of those who hate us are collapsing into Hell, while the doors of mercy are open to those who love us.
So those of you who love us - enjoy mercy. And those of you who hate us - enjoy Hell.
If a slave does not neglect our love, it is because of the good that Allah has placed in his heart.
If you love those who hate us then you do not love us, because our love and the love for those who hate us cannot be placed in the same heart. Allah says, “Allah has not made for any man two hearts in his breast” (33:4).
Therefore, you do not have two hearts to love: one heart devoted to our love and another heart devoted to the love of our enemies.
Therefore, those who love us are pure with our love just like pure gold.
We are the nobleones and our children are the children of the prophets. I am the successor of all the successors, and I am the party of Allah and His Messenger. The group of Shaytan are the oppressors.
Those of you who want to know if you love us should test your hearts.
If you find the love of those who incite hatred toward us in your heart, know that Allah, Jibraeel, and Mikaeel are your enemies, and that Allah is the enemy of the disbelievers.
Hadith 94; The Glad Tidings of Mustafa for the Shia of Murtadha
'O God, carry us in the ships of Thy deliverance, give us to enjoy the pleasure of whispered prayer to Thee, make us drink at the pools of Thy love, let us taste the sweetness of Thy affection and nearness, allow us to struggle in Thee, preoccupy us with obeying Thee, and purify our intentions in devoting works to Thee, for we exist through Thee and belong to Thee, and we have no one to mediate with Thee but Thee!' Imam Sajjad ('A); Sahifa al-Sajjadiyya
