(Al-Ahraf) 7 : 86
وَلَا تَقْعُدُوا بِكُلِّ صِرَاطٍ تُوعِدُونَ وَتَصُدُّونَ عَنْ سَبِيلِ اللَّهِ مَنْ آمَنَ بِهِ وَتَبْغُونَهَا عِوَجًا ۚ وَاذْكُرُوا إِذْ كُنْتُمْ قَلِيلًا فَكَثَّرَكُمْ ۖ وَانْظُرُوا كَيْفَ كَانَ عَاقِبَةُ الْمُفْسِدِينَ
And you shouldn't lurk along every path threatening people and hindering the believers against Lord Allah’s way and intending to make it crooked, and you remember when you were a few, then He multiplied you, and you see how was the consequence of the mischief-makers.
