Hadith 45
trials-afflictionsdeath
45 - وعن أبي عبد الله (ع) قال إنّ العبدَ يكون له عِند ربّه درجَةٌ لا يبلُغُها بعَمَله فيُبتلى في جسده أو يُصاب في ماله أو يصاب في ولده، فإنْ هو صَبر بَلَّغَه الله إيّاها.
45. It has been narrated that Abu 'Abd Allah (a.s) said: A person may have a status with his Lord that he cannot attain by his actions. Therefore, he is tried with his body or tried with his possessions, or he is tried with his children. And if he bears patience, Allah raises him to that status.
