إِن تُصِبۡكَ حَسَنَةٞ تَسُؤۡهُمۡۖ وَإِن تُصِبۡكَ مُصِيبَةٞ يَقُولُواْ قَدۡ أَخَذۡنَآ أَمۡرَنَا مِن قَبۡلُ وَيَتَوَلَّواْ وَّهُمۡ فَرِحُونَ ٥٠
If good befalls you, it distresses them; but if disaster strikes you, they say, "We took our matter [in hand] before,"1 and turn away while they are rejoicing.
Translation: Saheeh International (English)
1 The hypocrites claim to have protected themselves by remaining behind.
Each word's meaning and sound
If the Messenger of Allah receives a blessing from Allah that pleases him, such as victory or some gains, they dislike this, and it grieves them. If a misfortune befalls him in the form of some hardship or loss in battle, these hypocrites say that they had taken precautions for themselves, making the right decision when they did not go out to fight as the believers did, which led to them being killed or captured. They, then, turn away to their people, rejoicing in their own safety.
