Paradise as a reward

Abu Huraira رضي الله عنه narrated that Allah's Apostle صلي الله عليه و سلم said,

"Allah says, 'I have nothing to give but Paradise as a reward to my believer slave, who, if I cause his dear friend (or relative) to die, remains patient (and hopes for Allah's Reward)"

[sahih al-Bukhari, vol 8, Book 76, #432]
