Al-Ghaffar
Allah is Al-Ghafaar and Al-Ghafoor. He sees ours sins and disobedience, yet he will still forgive and accept repentance of all those who turn to Him. He shows never ending compassion and forgives any sin, small or big, of his worshipers.
From the root gh-f-r which has the following classical Arabic connotations: to cover, veil, conceal, hide to pardon, to forgive, to set aright, to cover a thing to protect it from dirt.

Would You destroy us for what the foolish among us have done? This is not but Your trial by which You send astray whom You will and guide whom You will. You are our Protector, so forgive us and have mercy upon us;
and You are the best of forgivers. (7:155)
