Shaykh Tusi has narrated through authentic chains of narrators from Ibn Abbas that Amirul Momineen (a.s.) used to attend the Prophet every morning and the latter also liked his visits most. He came one day and saw that the Holy Prophet (S) was sleeping in the courtyard and his holy head was in the lap of Dahiya Kalbi. Imam Ali (a.s.) said: “Peace be upon you, how is the Holy Prophet (S)?”
Dahiya said: “O brother of the Messenger, he is well.” Imam Ali (a.s.) said: “May Allah, give you a good reward.” Dahiya said: “I like you and I have brought a gift for you. You are the chief of believers and one who will take your followers to Paradise. After the Prophet you are the best of the creatures. On Judgment Day, Liwaul Hamd will be carried by you. You and your Shias will be the first to enter Paradise with the Prophet.
One who is devoted to you has obtained deliverance. And deprived of deliverance is one who denies your Wilayat. Whoever loved, loved Muhammad (S) and whoever hates you is in fact inimical to you because of his enmity to the Prophet and he is deprived of the intercession of the Prophet. Come near me, because you are deserving of this.” and he gave the Prophet’s head into his lap and went away.
When the Messenger of Allah (S) awoke, he asked: “Who was it that you were speaking to?” Imam Ali (a.s.) replied: “It was Dahiya Kalbi.” He said: “No, he was Jibraeel and he called you by the title that the Almighty Allah has given you. It is the Almighty Allah who has inculcated the hearts of believers with your love and your awe is put into the infidels.
