Translation:

2. Therefore to thy Lord turn in Prayer and Sacrifice.

Notes (Tafseer)

6287. He who grants these blessings is Allah, and to Allah alone must we turn in adoration and thanksgiving, and in sacrifice. Nahr=sacrifice: in a restricted ritual sense, the sacrifice of camels: see n. 2813 to xxii. 36. But the ritual is a mere Symbol. Behind it is a deep spiritual meaning: the meat slaughtered feeds the poor, and the slaughter is a symbol of the self-sacrifice in our hearts. "It is not their meat nor their blood, that reaches Allah: it is your piety that reaches Him" (xxii. 37).
