Al-Baqarah 2:54 واذ قال موسى لقومه يا قوم انكم ظلمتم انفسكم باتخاذكم العجل فتوبوا الى باريكم فاقتلوا انفسكم ذالكم خير لكم عند باريكم فتاب عليكم انه هو التواب الرحيم ٥٤
وَإِذۡ
قَالَ
مُوسَىٰ
لِقَوۡمِهِۦ
يَٰقَوۡمِ
إِنَّكُمۡ
ظَلَمۡتُمۡ
أَنفُسَكُم
بِٱتِّخَاذِكُمُ

أَنفُسَكُمۡ
ذَٰلِكُمۡ
خَيۡرٞ

And (remember) when Mûsâ (Moses) said to his people: "O my people! Verily, you have wronged yourselves by worshipping the calf. So turn in repentance to your Creator and kill yourselves (the innocent kill the wrongdoers among you), that will be better for you with your Creator." Then He accepted your repentance. Truly, He is the One Who accepts repentance, the Most Merciful.
