They challenge you to bring doom upon them, rather than turning righteous! Sufficient precedents have been set for them in the past. Indeed, your Lord is full of forgiveness towards the people, in spite of their transgressions, and your Lord is also strict in enforcing retribution.
وَيَستَعجِلونَكَ بِالسَّيِّئَةِ قَبلَ الحَسَنَةِ وَقَد خَلَت مِن قَبلِهِمُ المَثُلٰتُ وَإِنَّ رَبَّكَ لَذو مَغفِرَةٍ لِلنّاسِ عَلىٰ ظُلمِهِم وَإِنَّ رَبَّكَ لَشَديدُ العِقابِ
wa yasta’jiloonaka bis saiyi’ati qablal hasanati wa qad khalat min qablihimul masulaat; wa inna Rabbaka lazoo maghfiratil linnaasi ‘alaa zulmihim wa inna Rabbaka lashadeedul ‘iqaab
