Mercy of our Lord

[abo khbab]

Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (PBUH) said, "By the One in Whose Hand my soul is! If you do not commit sins, Allah would replace you with a people who would commit sins and seek forgiveness from Allah; and Allah will certainly forgive them.''
[Muslim].
Commentary: This Hadith does not mean that Allah likes disobedience. But by this way of description, the aim is to emphasize the importance of seeking forgiveness from Allah. We know that every man commits sins. But Allah likes those people who, after committing a sin, do not stick to it, but right away seek forgiveness for their sins from Allah. They weep and express sorrow before Allah. By seeking forgiveness, a relationship with Allah is established between man and his Creator. So seeking forgiveness is a very good act.
