§ Of the Return of the Noldor The Silmarillion

There Maedhros in time was healed; for the fire of life was hot within him, and his strength was of the ancient world, such as those possessed who were nurtured in Valinor. His body recovered from his torment and became hale, but the shadow of his pain was in his heart; and he lived to wield his sword with left hand more deadly than his right had been. By this deed Fingon won great renown, and all the Noldor praised him; and the hatred between the houses of Fingolfin and Fëanor was assuaged. For Maedhros begged forgiveness for the desertion in Araman; and he waived his claim to kingship over all the Noldor, saying to Fingolfin: 'If there lay no grievance between us, lord, still the kingship would rightly come to you, the eldest here of the house of Finwë, and not the least wise.' But to this his brothers did not all in their hearts agree.
