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