قُلْ لِّلَّذِيْنَ كَفَرُوْۗا اِنْ يَّنْتَہُوْا يُغْفَرْ لَہُمْ مَّا قَدْ سَلَفَ۰ۚ وَاِنْ يَّعُوْدُوْا فَقَدْ مَضَتْ سُـنَّۃُ الْاَوَّلِيْنَ۳۸
Qul lillatheena kafaroo in yantahoo yughfar lahum ma qad salafa wain yaAAoodoo faqad madat sunnatu alawwaleena
You tell the unbelievers in case they desist whatever has happened will be forgiven them. If they persist, they should remember the fate of those who have gone before them.
