We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 And We found most of them not true to their words; and indeed We found most of them disobedient. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them.
