Abu Hurairah (RAA) narrated that The Messenger of Allah (P.B.U.H.) said, “He who dies without having gone or thought of going out for Jihad in the Cause of Allah, will die while being guilty of having one of the qualities of hypocrisy.” Related by Muslim.

"Al-Haya' and Al-'Iy are two branches of faith, and Al-Badha and Al-Bayan are two branches of Hypocrisy."

"Whoever would like to meet Allah tomorrow as a Muslim, let him regularly attend these five (daily) prayers whenever the call for them is given (that in the mosques), for Allah prescribed for His Prophet the ways of guidance, and they (the prayers) are part of those ways of guidance. I do not think that there is anyone among you who does not have a place where he prays in his house. But if you were to pray in your houses and forsake the Masjids, you would be forsaking the Sunnah of your Prophet, and if you were to forsake the Sunnah of your Prophet you would go astray. There is no Muslim slave who performs Wudu and does it well, then walks to the prayer, but Allah will record one Hasanah (good deed) for each step he takes, or raise' him one level by it or erase one sin from him. I remember how we used to take short steps, and I remember (a time) when no one stayed behind from the prayer except a hypocrite whose hypocrisy was well known. And I have seen a man coming Supported by two others until he would be made to stand in the row."

He who likes to meet Allah tomorrow (i.e., on the Day of Requital) as a Muslim, should take care and observe the Salat when the Adhan is announced for them. Allah has expounded to your Prophet (PBUH) the ways of right guidance, and these (the prayers) are part of the right guidance. If you have to perform Salat in your houses, as this man who stays away (from the mosque) and performs Salat in his house, you will abandon the Sunnah (practice) of your Prophet (PBUH), and the departure from the Sunnah of your Prophet (PBUH) will lead you astray. I have seen the time when no one stayed behind except a well-known hypocrite. I also saw that a man was brought swaying (on account of weakness) between two men till he was set up in a row (in the mosque).

[Muslim].

(1) a believer who strives with his property and person in God’s path and when he meets the enemy fights till he is killed. (Of him the Prophet said that that martyr who has suffered trial is in God's tent under- His Throne and is not excelled by the prophets except in the degree of the prophetic office.) (2) A believer who mingles a good deed with another which is evil, who fights with his person and property in God’s path, fighting till he is killed when he meets the enemy. (Of him the Prophet said that it is a cleansing agent which has obliterated his sins and his errors, for the sword obliterates errors, and he will be introduced by whichever of the gates of paradise he wishes.) (3) A hypocrite who strives with his person and property, and when he meets the enemy fights till he is killed; but that one will go to hell, for the sword does not obliterate hypocrisy.” Darimi transmitted it.

"Whoever would like to meet Allah tomorrow (i.e. on the Day of Judgment) as a Muslim, let him preserve these five (daily) prayer when the call for them is given, for they are part of the ways of guidance, and Allah prescribed the ways of guidance to your Prophet. By Allah, if each of you prays in his house, you will have abandoned the Sunnah of your Prophet, and if you abandon the Sunnah of your Prophet you will go astray. I remember when no one stayed behind from the prayer except a hypocrite who was known for his hypocrisy. I have a man coming supported by two others, until he joined the row (of worshippers). There is no man who purifies himself and does it well, and comes to the mosque and prays there, but for every step that he takes, Allah raises him in status one degree thereby, and takes away one of his sins."

Mu'adh bin Jabal used to narrate something that the Companions of the Messenger of Allah had not heard, and he used to keep quiet about what they had heard. News of this report reached 'Abdullah bin 'Amr, and he said: "By Allah, I never heard the Messenger of Allah say this, and Mu'adh will put you into difficulty with regard to relieving yourself." News of that reached Mu'adh, so he met with him ('Abdullah). Mu'adh said: "O 'Abdullah! Denying a Hadith from the Messenger of Allah is hypocrisy, and its sn is upon the one who said it (if it is not true). I did indeed hear the Messenger of Allah say: 'Beware of the three things which provoke curses: Relieving oneself in watering places, in places of shade and in the middle of the street.'"

Allah's Messenger said: "Whoever performs Salat for Allah for forty days in congregation, catching the first Takbir, two absolutions are written for him: absolution from the Fire, and absolution from the Fire, and absolution from hypocrisy."
