My lil cousin asked me this morning "what's the significance of Eid ul Adha". I smiled and said: " it's the tradition of prophet Ibrahim(AS), that started when Ibrahim was asked to sacrifice his son to Allah.
Despite the fact that he had his son Ismaeel in his old days and they have no hope of conception again. Ibrahim has been going througj tests and trials since he was a child.
Born into a family of idolators, he did not agree with their way and constantly seeks for the face of his Lord. He pondered day and night and wondered if the sun and the moon could be the Lord of the worlds but he soon realised that they couldn't be, since they are not permanent, they come and go and as such, the Lord of the world has to be permanent.
He also was tested when his people threw him into a blazing fire for destroying their idols and blaming it on the bigger idols, the idolators said that he knows that they cannot speak and Ibrahim replied that 'why would they worship something like that ?...it cannot cause them harm, nor benefit, cannot speak, see or move on it own.
The people were outraged, so they set a blazing furnace and cast Ibrahim into it. But by Allah's might, he didn't burn. He survived without a single scald.
Thereafter, Ibrahim (AS) left his home in his continued search for Allah, when He was Inpired by Allah, He left with his wife until they got to a barren and deserted land without water nor shelter. He left his family there in the hands of Allah, putting his total trust in him since it was he (Allah) that asked them to stay there.
All these shows his total and complete devotion and sincererity to Allah.
The most significant part you'll like to hear is when Allah also asked him to sacrifice his son and he accepted and submitted fully to Allah's will. But lo and behold! Allah replaced the son with a sacrificial cattle to be slaughtered for his sake. His son was not slaughtered too" "Now imagine another human going though all these, won't he say that this is too much? Won't he stop worshiping Allah and flee? Even though it's impossible to flee from Allah? .
Indeed it is our submission that Allah needs not our sacrifice.
