Laknatullah Israel

Assalamualaikum all my friends,
Ill just let you know that the "laknatullah israel"because it means "may Allah curse Israel".
First of all, we should not curse anyone.
One time resulullah used to curse some of the mushrekeen and Allah swt told him not to do that because the matter is not his of rasullullah saw why, because later on, all those mushreekeen were guided to islaam.
In arabaic lak'natullah , to curse someone means that may that person or thing be removed far from ALlah's mercy.
Instead, it is better to say "may Allah guide them to islam".
On the day of Taif when rasulullah saw went to give dawah to them, they stoned him that the shoes were filled with blood.
It is said that the prophet told that this was the hardest day of his life.
But, when he left Taif Allah sent Angel of mountains to give him order to crush people of Taif with the two mountains surrounding it.
He could have said "yes, crush them punks".

However, he mentioned that they do not know and maybe their ofspring will become muslims, and that is what happened.Also check the following
