Surah At-Tawbah, Verse 42

لَوۡ كَانَ عَرَضٗا قَرِيبٗا وَسَفَرٗا قَاصِدٗا لَّٱتَّبَعُوكَ وَلَٰكِنۢ بَعُدَتۡ عَلَيۡهِمُ ٱلشُّقَّةُۚ وَسَيَحۡلِفُونَ بِٱللَّهِ لَوِ ٱسۡتَطَعۡنَا لَخَرَجۡنَا مَعَكُمۡ يُهۡلِكُونَ أَنفُسَهُمۡ وَٱللَّهُ يَعۡلَمُ إِنَّهُمۡ لَكَٰذِبُونَ٤٢

law kāna ʿaraḍan qarīban wasafaran qāṣidan la-ittabaʿūka walākin baʿudat ʿalayhimu l-shuqatu wasayaḥlifūna bil-lahi lawi is'taṭaʿnā lakharajnā maʿakum yuh'likūna anfusahum wal-lahu yaʿlamu innahum lakādhibūna

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