Allah consoles His Prophet Muhammad for the disbelief of his people and gives him the glad tidings of good consequences and victory in this world and the Hereafter, as happened to Musa bin 'Imran, peace be upon him, whom Allah sent with clear proof and definitive evidence. Allah says: {with Our Ayat, and a manifest authority}. Authority means proof and evidence. {to Fir'awn}, who was the king of the Copts of Egypt. {Haman} who was his adviser. {and Qarun} who was the richest trader among the people of his time. {but they called (him): "A sorcerer, liar!"} means, they rejected him and thought he was a sorcerer, a madman and an illusionist who was telling lies about having been sent by Allah. This is like the Ayah: {Likewise, no Messenger came to those before them but they said: "A sorcerer or a madman!" Have they transmitted this saying to these? Nay, they are themselves a people transgressing beyond bounds!} (51:52-53) {Then, when he brought them the Truth from Us,} means, with definite evidence that Allah had sent him to them, {they said: "Kill with him the sons of those who believe and let their women live;} This was a second command from Fir'awn to kill the males of the Children of Israel. The first command had been as a precaution against the emergence of a man like Musa, or an act intended to humiliate this people or reduce their numbers or both. The second command was for the second reason, to humiliate the people so that they would regard Musa as a bad omen, they said: {'We (Children of Israel) had suffered troubles before you came to us, and since you have come to us." He said: "It may be that your Lord will destroy your enemy and make you successors on the earth, so that He may see how you act?"} (7:129). Qatadah said, this was one command after another. {but the plots of disbelievers are nothing but in vain!} means, their schemes and intentions - to reduce the numbers of the Children of Israel lest they prevail over them - were doomed to failure. It was reported in the Hadith narrated from Abu Musa, may Allah be pleased with him, that when the Messenger of Allah was afraid of some people, he would say: «O Allah, we seek refuge in You from their evil and we seek Your help in repulsing them.»
