يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْا مَا لَكُمْ اِذَا قِيْلَ لَكُمُ انْفِرُوْا فِيْ سَبِيْلِ اللّٰهِ اثَّاقَلْتُمْ اِلَى الْاَرْضِۗ اَرَضِيْتُمْ بِالْحَيٰوةِ الدُّنْيَا مِنَ الْاٰخِرَةِۚ فَمَا مَتَاعُ الْحَيٰوةِ الدُّنْيَا فِى الْاٰخِرَةِ اِلَّا قَلِيْلٌ ( التوبة: ٣٨ )
Yaaa aiyuhal lazeena aamanoo maa lakum izaa qeela lakumun firoo fee sabeelil laahis saaqaltum ilal ard; aradeetum bilhayaatid dunyaa minal Aakhirah; famaa ma taaul hayaatiddunyaa fil Aakhirati illaa qaleel (at-Tawbah 9:38)
O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little. (At-Tawbah  : 38)
1 Mufti Taqi Usmani
O you who believe, what is wrong with you that when it is said to you, “Come out in the way of Allah,” you turn heavy (and cling) to the ground. Have you become happy with the worldly life instead of the Hereafter? So, (remember that) the enjoyment of the worldly life is but trivial in (comparison with) the Hereafter.
