Book Name:Qaroon Ki Halakat Ka Sabab
Qaroon was a very handsome man. He was a great scholar of Tawrah in Bani Israel. He was very sociable and well-mannered but as he acquired enormous wealth he got totally changed and became a bitter enemy of Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام. He also became arrogant. When the commandment of Zakah revealed, he promised in front of Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام that he will pay a 1/1000 of his entire wealth as Zakah but when he calculated his wealth and possessions, he learnt that he had to pay a huge amount of money as Zakah.
Having seen this he became at once greedy and stingy and not only did he deny himself to pay Zakah but he also started luring Bani Israel into not paying Zakah under the pretext of paying Zakah Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام wants to gain your wealth. He even went to the extent that he played a trick in order to mislead people about Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام by convincing a woman after giving her a lot of money to blame Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام of adultery.
Therefore, right at the time when Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام was delivering a speech, Qaroon interrupted him. Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام asked Qaroon to bring that woman in front of him. The woman was called upon and Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام said, ‘O lady, swear by Allah عَزَّوَجَلَّ Who split the river for the people of Israel and helped them get rid of pharaoh by crossing it safely. Tell me truthfully what the matter is.’ Due to the dignity of Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام the woman started trembling and confessed openly in the public, ‘O Nabi of Allah عَزَّوَجَلَّ! Qaroon enticed me to slander against you by giving me enormous wealth.’ On that time, tears streamed down Sayyiduna Musa’s face and he عَـلَيْـهِ الـسَّـلَام performed Sajdah to thank Allah عَزَّوَجَلَّ and made this Du’a: ‘O Allah عَزَّوَجَلَّ, inflict Your wrath upon Qaroon’. He عَـلَيْـهِ الـسَّـلَام then addressed the congregation: The one who is with Qaroon should stay with him and the one who is with me should separate from Qaroon. All the Bani Israel left Qaroon except two people. Afterwards, Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام ordered the earth: O earth! Seize him. Qaroon immediately sank into the earth up to his knees. He عَـلَيْـهِ الـسَّـلَام again gave the same command to the earth and Qaroon sank into the earth up to his waist. Having seen this Qaroon invoked Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام for mercy for the sake of his relations with Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام by crying and begging. But Sayyiduna Musa عَـلَيْـهِ الـسَّـلَام paid no attention to it.
