Surat At-Tawbah (38-39)

{يَا أَيُّهَا الَّذِينَ آمَنُواْ مَا لَكُمْ إِذَا قِيلَ لَكُمُ انفِرُواْ فِي سَبِيلِ اللّهِ اثَّاقَلْتُمْ إِلَى الأَرْضِ أَرَضِيتُم بِالْحَيَاةِ الدُّنْيَا مِنَ الآخِرَةِ فَمَا مَتَاعُ الْحَيَاةِ الدُّنْيَا فِي الآخِرَةِ إِلاَّ قَلِيلٌ} [التوبة: 38]

38- O believers, why did you lag behind when you were asked to go for Jihad in the battle of Tabuk? You showed negligence and hated the troubles of Jihad and heat, and inclined to comfort, enjoying worldly pleasures, and ripe fruits as the battle was in the time of reaping.

Did you satisfy with the temporary world rather than the Hereafter and its permanent blessings? Let it be known that enjoying worldly life and its pleasures is incomparable with the pleasures of the Hereafter.

{إِلاَّ تَنفِرُواْ يُعَذِّبْكُمْ عَذَاباً أَلِيماً وَيَسْتَبْدِلْ قَوْماً غَيْرَكُمْ وَلاَ تَضُرُّوهُ شَيْئاً وَاللّهُ عَلَى كُلِّ شَيْءٍ قَدِيرٌ} [التوبة: 39]

39- If you do not go for Jihad which the Prophet (peace be upon him) called you to, Allah shall punish you with destruction, drought, and other painful punishments then Allah shall bring better people to fight along with His Prophet, obey and support him, and prefer the Hereafter to the world. You shall not harm Allah by lagging behind from Jihad, for He is capable of providing you with victory and nothing can fail him. He is All-Able but harm goes back to you.
