Abdullah bin Masud (Radiyallaahu `anhu) reported the Prophet (Sallallaahu `alayhi wa sallam) said,
“”Truth leads to piety and piety leads to Heaven. A man persists in speaking the truth till he is enrolled with God as a truthful. Falsehood leads to vice andvice leads to the Fire (Hell), and a person persistson telling lies until he is enrolled as a liar”

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.’”

Narrated on the authority of ‘Abdullah b. Mas’ud (Radiyallaahu `anhu) that the Messenger of Allah (Sallallaahu `alayhi wa sallam) observed,
“None shall enter the Fire (of Hell) who has in his heart the weight of a mustard seed of Iman and none shall enter Paradise who has in his heart the weight of a mustard seed of pride.”

Narrated Abu Huraira (Radiyallaahu `anhu), The Prophet (Sallallaahu `alayhi wa sallam) said,
“Allah will prepare for him who goes to the mosque (every) morning and in the afternoon (for the congregational prayer) an honorable place in Paradise with good hospitality for (what he has done) every morning and afternoon goings.”

The Prophet (Sallallaahu `alayhi wa sallam) said,
“There is a tree in Paradise (which is so big and huge that) if a rider travels in its shade for one hundred years, he would not be able to cross it.”
