It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him), he says: I came to the Messenger of Allah (peace and blessings be upon him) while he was sitting in the mosque. I came and sat down. The Messenger of Allah (peace and blessings be upon him) said: O Abu Dharr! Have you prayed? I said: No. He (peace and blessings be upon him) said: Get up and pray. So I prayed and then sat down. The Messenger of Allah (peace and blessings be upon him) said: O Abu Dharr! Seek refuge with Allah from the devils among mankind and jinn. I said: O Messenger of Allah! Are there devils among mankind too? He (peace and blessings be upon him) said: Yes, absolutely. I said: O Messenger of Allah! Tell me something about prayer. He (peace and blessings be upon him) said: It is the best thing that has been made; whoever wishes may pray less, and whoever wishes may pray more. I said: O Messenger of Allah! (Tell me about) fasting. He (peace and blessings be upon him) said: It is such an obligation that its reward will also be given, and with Allah there is much more besides. I said: O Messenger of Allah! (Tell me about) charity. He (peace and blessings be upon him) said: It will be multiplied many times. I said: O Messenger of Allah! Which charity is best? He (peace and blessings be upon him) said: That which is given by a person of little means according to his capacity, or given secretly to a poor person. I said: O Messenger of Allah! Who was the first prophet? He (peace and blessings be upon him) said: Adam (peace be upon him). I said: Was Adam (peace be upon him) a prophet? He (peace and blessings be upon him) said: Yes, he was a prophet and he was spoken to. I said: O Messenger of Allah! How many messengers are there? He (peace and blessings be upon him) said: About three hundred and fifteen or sixteen. In one narration: Three hundred and fifteen, a great multitude. I said: O Messenger of Allah! What is the greatest thing revealed to you? He (peace and blessings be upon him) said: Ayat al-Kursi {اَللّٰہُ لَا اِلٰہَ اِلَّا ھُوَ الْحَیُّ الْقَیُّوْمُ}. In one narration, he (peace and blessings be upon him) recited the entire verse.
