Anas b. Malik reported:The Paradise is surrounded by hardships and the Hell-Fire is surrounded by temptations.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، وَحُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " حُفَّتِ الْجَنَّةُ بِالْمَكَارِهِ وَحُفَّتِ النَّارُ بِالشَّهَوَاتِ " .
