The Prophet, may Allah bless him and grant him peace, asked Haritha R.A. , “Harithah, how are you this morning?” He said, “This morning I have become a true mumin.” He said, “Think about what you are saying! Because every statement has a reality.” He said, “Messenger of Allah, my self dislikes the world, so that it is sleepless at night and thirsty in the day, and it is as if I am gazing upon the Throne of my Lord appearing, and it is as if I am gazing upon the people of the Garden in the Garden and how they visit each other in it, and as if I am gazing upon the people of the Fire and how they howl in it.” He said, “You have seen, so remain firm. [You are] a slave whom Allah has illuminated the iman in his heart.” (Tabarani in al-Kabeer)
Imam Ibn Rajab al-Hanbali says in Jami’ al-’Ulum wa’l-Hikam in the Commentary on the Second Hadith : “The famous hadith of Harithah has been narrated in various ways, in some of which it is mursal [attributed to the Prophet but without the connecting link of the person among the Followers who narrated it from the Companion] and also with a full chain of transmission, but the mursal form is more authentic.
(In Kanz al-’Ummal, the hadith is ascribed to Anas, may Allah be pleased with him, and is from Ibn ‘Asakir, al-’Askari in al-Amthal, and Ibn an-Najjar. Al-Haythami in Majma’ az-Zawa’id ascribes it to al-Bazzar narrating from Anas and at-Tabarani in al-Kabeer who narrates it from al-Harith ibn Malik himself. And Allah knows best. -Shaykh Abdus Samad Clark)
