Al-A'raf 7:149

Walamma suqita fee aydeehimwaraaw annahum qad dalloo qaloo la-in lam yarhamnarabbuna wayaghfir lana lanakoonanna mina alkhasireen

And when regret overcame them and they saw that they had gone astray, they said, "If our Lord does not have mercy upon us and forgive us, we will surely be among the losers."

When they became remorseful and saw that they had gone astray, they said, “If Allah shows no mercy to us, and does not forgive us, we shall certainly be among the losers.”
