إِنَّ هَٰذَا لَهُوَ الْبَلَاءُ الْمُبِينُ
Allah ﷻ created us to test us. Ebrahimعليه السلام put aside his feelings,logic etc & complied with the command of Allah ﷻ. Sometimes, a person feels that a test is too difficult to bear. This test of Ebrahim عليه السلام was such, that no one is asked to bear this. So Qurbani keeps this fresh in our mind every year, that the test I am going through, is incomparable to that test.
