(At-Thouba) 9 : 86
وَإِذَا أُنْزِلَتْ سُورَةٌ أَنْ آمِنُوا بِاللَّهِ وَجَاهِدُوا مَعَ رَسُولِهِ اسْتَأْذَنَكَ أُولُو الطَّوْلِ مِنْهُمْ وَقَالُوا ذَرْنَا نَكُنْ مَعَ الْقَاعِدِينَ
And when a Surath is revealed to believe in Lord Allah and to do Jihad with His Messenger, healthiest and wealthiest among them ask you exemption and they say: Leave us with those who are sitting.
