Al-A'raaf • EN-TAFSIR-IBN-ABBAS
﴿ قَالَ رَبِّ ٱغْفِرْ لِى وَلِأَخِى وَأَدْخِلْنَا فِى رَحْمَتِكَ ۖ وَأَنتَ أَرْحَمُ ٱلرَّٰحِمِينَ ﴾
“Said [Moses]: "O my Sustainer! Grant Thou forgiveness unto me and my brother, and admit us unto Thy grace: for Thou art the most merciful of the merciful!"”
(He) Moses (said: My Lord! Have mercy on me) because of what I did to Aaron (and on my brother) Aaron because he did not fight them; (bring us into Thy mercy) in Your Garden, (Thou the Most Merciful of all who show mercy) towards us.
