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 Abu Huraira (Radiyallahu `anhu) that the Prophet (Sallallaahu `alayhi wa sallam) said,
“The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again.

The Prophet (Sallallaahu `alayhi wa sallam) said,
“The greatest reward comes with the greatest trial. When Allah (Subhanahu wa-ta’ala) loves a people He tests them. Whoever accepts that wins His pleasure but whoever is discontent with that earns His wrath.”

Narrated Abu Huraira (Radiyallaahu `anhu), Allah’s Apostle (Sallallaahu `alayhi wa sallam) said,
“If Allah wants to do good to somebody, He afflicts him with trials.”
