Fatalaqqaaa Aadamu mir Rabbihee Kalimaatin fataaba 'alayh; innahoo Huwat Tawwaabur Raheem
Then Adam received from his Lord [some] words, and He accepted his repentance. Indeed, it is He who is the Accepting of Repentance, the Merciful.
1 Mufti Taqi Usmani
Then ’Ādam learned certain words (to pray with) from his Lord; so, Allah accepted his repentance. No doubt, He is the Most-Relenting, the Very-Merciful.
