﴿ قُلْ عَسَىٰٓ أَن يَكُونَ رَدِفَ لَكُم بَعْضُ ٱلَّذِى تَسْتَعْجِلُونَ ﴾

“say thou: “It may well be that something of that which [in your ignorance] you so hastily demands has already drawn close unto you.””

Say ‘It may be that part of what you seek to hasten on is close behind you’ — so they were slain at Badr and the remaining chastisement will come to them after death.
