﴿ وَإِذَآ أُنزِلَتْ سُورَةٌ أَنْ ءَامِنُوا۟ بِٱللَّهِ وَجَٰهِدُوا۟ مَعَ رَسُولِهِ ٱسْتَـْٔذَنَكَ أُو۟لُوا۟ ٱلطَّوْلِ مِنْهُمْ وَقَالُوا۟ ذَرْنَا نَكُن مَّعَ ٱلْقَٰعِدِينَ ﴾

“[They are indeed denying it:] for, when they were called upon through revelation, "Believe in God, and strive hard [in His cause] together with His Apostle," [even] such of them as were well able [to go to war] asked thee for exemption, saying, "Allow us to stay behind with those who remain at home!"”

And when a sūra that is a section of the Qur’ān is revealed saying ‘Believe in God and strive with His Messenger’ the affluent among them ask leave of you saying ‘Leave us to be with those who sit at home’.
