At-Taubah - 9:86

وَإِذَا أُنزِلَتْ سُورَةٌ أَنْ آمِنُواْ بِاللّهِ وَجَاهِدُواْ مَعَ رَسُولِهِ اسْتَأْذَنَكَ أُوْلُواْ الطَّوْلِ مِنْهُمْ وَقَالُواْ ذَرْنَا نَكُن مَّعَ الْقَاعِدِينَ
[9:86]
And whenever a chapter is revealed, saying: Believe in Allah and strive hard along with His Messenger, those having ampleness of means ask permission of you and say: Leave us (behind), that we may be with those who sit.
When a Sura comes down, enjoining them to believe in Allah and to strive and fight along with His Messenger, those with wealth and influence among them ask thee for exemption, and say: "Leave us (behind): we would be with those who sit (at home)."
And when a surah is revealed (which saith): Believe in Allah and strive along with His messenger, the men of wealth among them still ask leave of thee and say: Suffer us to be with those who sit (at home).
