81 Preface فَأَرَدنا أَن يُبدِلَهُما رَبُّهُما خَيرًا مِنهُ زَكاةً وَأَقرَبَ رُحمًاYusuf Ali“So we desired that their Lord would give them in exchange (a son) better in purity (of conduct) and closer in affection.1The son was practically an outlaw-a danger to the public and a particular source of grief to his righteous parents. Even so, his summary capital punishment would have been unjustified if Khidr had been acting on his own. But Khidr was not acting on his own: see the latter part of the next verse. The plural “we” also implies that he was not acting on his own. He was acting on higher authority and removing a public scourge, who was also a source of extreme sorrow and humiliation to his parents. His parents are promised a better-behaved son who would love them and be a credit to them.
