لَو كانَ عَرَضًا قَريبًا وَسَفَرًا قاصِدًا لَاتَّبَعوكَ وَلـٰكِن بَعُدَت عَلَيهِمُ الشُّقَّةُ ۚ وَسَيَحلِفونَ بِاللَّهِ لَوِ استَطَعنا لَخَرَجنا مَعَكُم يُهلِكونَ أَنفُسَهُم وَاللَّهُ يَعلَمُ إِنَّهُم لَكاذِبونَ

Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars.
