quran:27:72 –

Say, "Perhaps it is close behind you - some of that for which you are impatient.  

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.
القرآن:٢٧:٧٢ –

قُلْ عَسَىٰ أَنْ يَكُونَ رَدِفَ لَكُمْ بَعْضُ الَّذِي تَسْتَعْجِلُونَ  

{قل عسى أن يكون رَدِفَ} قرب {لكم بعض الذي تستعجلون} فحصل لهم القتل ببدر وباقي العذاب يأتيهم بعد الموت.
