I am angry about Palestine

Allah sends us tribulations for one of two reasons.
1. To remove our sins.
2. To raise our ranks.

Thats basically it. So when tribulation hits a Muslims is not bad, its good.

Make dua for these people when you feel the least powerful but know that dua is accepted in one of three ways.

1. In the Dunya now
2. Later in the dunya
3. Or later in Paradise

So which one is better? to receive the dua as good works in paradise.

Ibn Ata'llah As-Sakandari once said,
"You have not abandoned ignorance at all, if you want something to take place in any moment other than what Allah has manifested in it.

So don't be agrieved there is always hope. Also look at the history of the last hundred years when Muslims suffered but they were patient because they understood these things.
