4:170An-Nisaa

The Messenger of Allah (ﷺ) led us in the morning prayer at al-Hudaibiyyah after rain which has fallen during the night, and when he finished, he turned to the people and said: Do you know what your Lord has said ? They said: Allah and His Apostle know best. He said: This morning there were among mt servants one who believes in me and one who disbelieves. The one who said: "We have been given rain by Allah's grace and mercy" is the one who believes in me and disbelieves in the star ; but the one who said: "We have been given rain by such and such a rain star," is the one who disbelieves in me and believes in the star.

A man from the people of the scripture came to the Prophet (ﷺ) and said, "O Abal-Qasim! Allah will hold the Heavens upon a Finger, and the Earth on a Finger and the land on a Finger, and all the creation on a Finger, and will say, 'I am the King! I am the King!' " I saw the Prophet (after hearing that), smiling till his premolar teeth became visible, and he then recited: -- 'No just estimate have they made of Allah such as due to him... (39.67)

Son! You will not get the taste of the reality of faith until you know that what has come to you could not miss you, and that what has missed you could not come to you. I heard the Messenger of Allah (ﷺ) say: The first thing Allah created was the pen. He said to it: Write. It asked: What should I write, my Lord? He said: Write what was decreed about everything till the Last Hour comes. Son! I heard the Messenger of Allah (ﷺ) say : He who dies on something other than this does not belong to me.

One day while Allah's Messenger (ﷺ) was sitting with the people, a man came to him walking and said, "O Allah's Messenger (ﷺ). What is Belief?" The Prophet (ﷺ) said, "Belief is to believe in Allah, His Angels, His Books, His Apostles, and the meeting with Him, and to believe in the Resurrection." The man asked, "O Allah's Messenger (ﷺ) What is Islam?" The Prophet (ﷺ) replied, "Islam is to worship Allah and not worship anything besides Him, to offer prayers perfectly, to pay the (compulsory) charity i.e. Zakat and to fast the month of Ramadan." The man again asked, "O Allah's Messenger (ﷺ) What is Ihsan (i.e. perfection or Benevolence)?" The Prophet (ﷺ) said, "Ihsan is to worship Allah as if you see Him, and if you do not achieve this state of devotion, then (take it for granted that) Allah sees you." The man further asked, "O Allah's Messenger (ﷺ) When will the Hour be established?" The Prophet (ﷺ) replied, "The one who is asked about it does not know more than the questioner does, but I will describe to you its portents. When the lady slave gives birth to her mistress, that will be of its portents; when the bare-footed naked people become the chiefs of the people, that will be of its portents. The Hour is one of five things which nobody knows except Allah. Verily, the knowledge of the Hour is with Allah (alone). He sends down the rain, and knows that which is in the wombs." (31.34) Then the man left. The Prophet (ﷺ) said, "Call him back to me." They went to call him back but could not see him. The Prophet (ﷺ) said, "That was Gabriel who came to teach the people their religion." (See Hadith No. 47 Vol 1)
