What advice can you give to someone about the necessity of forgiving people and being patient with their annoyance?

Question

There is no one among us who does not make mistakes, and does not wrong other people. Each of us would like people to forgive him for all the wrongs he has done to them, so that they will not ask for restitution thereof on the Day of Resurrection. Allah Ta’ala says in the Noble Qur’an: Who spend [in the cause of Allah] during ease and hardship and who restrain anger and who pardon the people – and Allah loves the doers of good. (3:134) One best ways a Muslim can help himself to bear with patience whatever befalls him of annoyance from other people is to think of his own shortcomings. A Muslim can free his heart of grudges by showing sincerity towards the Muslims for the sake of Allah.
