الآية رقم (141) - وَلِيُمَحِّصَ اللّهُ الَّذِينَ آمَنُواْ وَيَمْحَقَ الْكَافِرِينَ

(141) - {And that Allah may purify the believers [through trials] and destroy the disbelievers.}

The hypocrites withdrew from the battle, and they were saying: If Muhammad had been a prophet, we would not have been defeated in Uhud… So it was a process of purification.

وَيَمْحَقَ الْكَافِرِينَ {and destroy the disbelievers.}: So things became clear and people were classified after the Battle of Uhud.
