Tafsir of Muhammad 47:31

ولنبلونكم

And We will surely try you, meaning, `We will surely test you with commands and prohibitions.'

حتى نعلم المجاهدين منكم والصابرين

ونبلو أخباركم

until We know those who strive among you and the patient, and We will put to a test all your affairs. There is absolutely no doubt that Allah's knowledge precedes the occurrence of all events. In this Ayah, "until We know'' means `until We know of its occurrence.' This is why Ibn Abbas said in regard to this and similar texts, "Except so that We may know, means, so that We may see.''
