Translation:

1. Have We not expanded thee thy breast?

Notes (Tafseer)

6188. Cf. the prayer of Moses in xx. 25. The breast is symbolically the seat of knowledge and the highest feelings of love and affection, the treasure-house in which are stored the jewels of that quality of human character which approaches nearest to the divine. The holy Prophet's human nature had been purified, expanded, and elevated, so that he became a Mercy to all Creation. Such a nature could afford to ignore the lower motives of ordinary humanity which caused shameful attacks to be made on him. Its strength and courage could also bear the burden of the galling work which it had to do in denouncing sin, subduing it, and protecting Allah's creatures from its oppression.
