Abu Hurairah (Radiyallaahu `anhu) reported Allah’s Messenger (Sallallaahu `alayhi wa sallam) said:
“The servant speaks words that he does not understand its repercussions but he sinks down in Hell-Fire farther than the distance between the east and the west.”

Anas ibn Malik (Radiyallaahu `anhu) narrated that the Messenger of Allah (Sallallaahu `alayhi wa sallam) said,
“The Paradise is surrounded by hardships and the Hell-Fire is surrounded by temptations.’”

Narrated by ‘Ali (Radiyallahu `anhu), the Prophet (Sallallaahu `alayhi wa sallam) said,
“Do not tell a lie against me for whoever tells a lie against me (intentionally) then he will surely enter the Hell-fire”

It is narrated on the authority of Jabir b. Abdullah: I heard the Messenger of Allah (Sallallaahu `alayhi wa sallam) saying,
“He who met Allah without associating anything with Allah entered Paradise and he who met Him associating (anything) with Him entered Fire.”

The Prophet of Allah (Sallallaahu `alayhi wa sallam) said,
“The first matter that the slave will be brought to account for on the Day of Judgment is the prayer. If it is sound, then the rest of his deeds will be sound. And if it is bad, then the rest of his deeds will be bad”

Narrated Abu Huraira (Radiyallaahu `anhu) that the Prophet of Allah (Sallallaahu `alayhi wa sallam) said,
“Sometimes one may utter a word without thinking whether it is right or wrong and because of that he may slip down in the Fire as far away as the East is from the West.”

The Messenger of Allah (Sallallaahu `alayhi wa sallam) said,
“He who commits suicide by throttling shall keep on throttling himself in the hell fire (forever) and he who commits suicide by stabbing himself shall keep on stabbing himself in the hell fire.”

The Messenger of Allah (Sallallaahu `alayhi wa sallam) said,
“Paradise and Hell-fire disputed together, and Hell-fire said: ‘In me are the mighty and the haughty.’ Paradise said: ‘In me are the weak and the poor.’ So Allah judged between them, [saying]: ‘You are Paradise, My mercy; through you I show mercy to those I wish. And you are Hell-fire, My punishment; through you I punish those I wish, and it is incumbent upon Me that each of you shall have its fill.’”

Adi Bin Hatim (Radiyallaahu `anhu) reported: Messenger of Allah (Sallallaahu `alayhi wa sallam) said,
“Protect yourself from the Hell-fire even by giving a piece of a date as charity.”
