It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to teach us these words: "O Allah, set right our mutual relations, join our hearts together, guide us to the paths of peace, bring us out of the darkness into the light, and keep us away from indecencies, the apparent and the hidden. O Allah, bless us in our hearing, our sight, our hearts, our wives and our offspring, and accept our repentance; indeed You are the Most Accepting of repentance, the Most Merciful. Make us grateful for Your blessing, praising it and speaking of it, and complete it for us."
