How can Allah be both just and merciful?

- How can Allah be just and merciful at the same time?
- I want to explain my question by giving an example; Suppose that person A killed person B... after killing, he felt guilty. He repented to Allah. What will happen on the Day of Resurrection ... If Allah forgives him ..., is it not unfair to person B (because A will not be punished if Allah forgives him)? ... And if He does not forgive A, He is not regarded as merciful ... I hope you understand my questions ... I am waiting for your answer.

Dear Brother / Sister,

Those two concepts are not opposites; rather, they are mutually reinforcing concepts that can always come together. It can even be said that there is mercy in all justice, but there might not be justice in all mercy.

“The woman and the man guilty of adultery or fornication,- flog each of them with a hundred stripes: Let not compassion move you in their case, in a matter prescribed by Allah, if ye believe in Allah and the Last Day: and let a party of the Believers witness their punishment..” (an-Nur, 24/2)

It is possible to see that fact in the verse above.

As for the issue mentioned in the question:

When Allah forgives a servant for his wrongdoing, He will give such rewards to the other servant that he will not even think about the wrongdoing; in fact, he himself will consent to it and will gladly waive his right.

For example, if a person who buried his child alive became a Muslim and reached the rank of a Companion, that child would be given such blessings, such rewards, such positions and ranks that he would be pleased with what happened to him, let alone claiming rights.

It should not be forgotten that Allah is the one who punishes and rewards, and Allah is the one who knows who deserves punishment and reward. It is regarded as justice, mercy and wisdom to act accordingly.
