Forgive people and Allah will forgive you!

بسم الله الرحمن الرحيم

In The Name of Allah, The Most Mercy, The Bestower of Mercy.

The Messenger, peace and blessings of Allah be upon him, said: “Forgive (or pardon people) and you will be forgiven”.

Al-Allamah Zayd Bin Hadi Al-Mad’khali, may Allah have mercy upon him, said:

This statement of the Prophet, peace and blessings of Allah be upon him, “Forgive (or pardon people) and you will be forgiven” is a clarification that reward is given in accordance with the deed performed – that if a person is one with a forgiving character when taking, giving, buying and selling, and when dealing with his family, neighbours and companions; rather when dealing with the society and people -wherever that may be, then indeed reward given in accordance with the deed. He will be forgiven – meaning, Allah will forgive him by making his affairs easy, forgive him by wiping away his sins and facilitate him with people who will deal with him in the same manner he deals with (other) people.
