Those will have lost who killed their children in foolishness without knowledge and prohibited what Allah had provided for them, inventing untruth about Allah. They have gone astray and were not [rightly] guided.
اردو — مودودی
یقیناً خسارے میں پڑ گئے وہ لوگ جنہوں نے اپنی اولاد کو جہالت و نادانی کی بنا پر قتل کیا اور اللہ کے دیے ہوئے رزق کو اللہ پر افترا پردازی کر کے حرام ٹھیرا لیا یقیناً وہ بھٹک گئے اور ہرگز وہ راہ راست پانے والوں میں سے نہ تھے
Bahasa Indonesia — Kemenag
Sesungguhnya rugilah orang yang membunuh anak-anak mereka, karena kebodohan lagi tidak mengetahui dan mereka mengharamkan apa yang Allah telah rezeki-kan pada mereka dengan semata-mata mengada-adakan terhadap Allah. Sesungguhnya mereka telah sesat dan tidaklah mereka mendapat petunjuk.
Ibn Kathir
Allah says that those who committed these evil acts have earned the loss of this life and the Hereafter.
As for this life, they lost when they killed their children and made it difficult for themselves by prohibiting some types of their wealth, as an act of innovation that they invented on their own. As for the Hereafter, they will end up in the worst dwellings, because they used to lie about Allah and invent falsehood about Him. Allah also said,
قُلْ إِنَّ الَّذِينَ يَفْتَرُونَ عَلَى اللَّهِ الْكَذِبَ لاَ يُفْلِحُونَ - مَتَـعٌ فِى الدُّنْيَا ثُمَّ إِلَيْنَا مَرْجِعُهُمْ ثُمَّ نُذِيقُهُمُ الْعَذَابَ الشَّدِيدَ بِمَا كَانُواْ يَكْفُرُونَ
(Say: "Verily, those who invent a lie against Allah will never be successful." (A brief) enjoyment in this world! And then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve.) 10:69-70 Al-Hafiz Abu Bakr bin Marduwyah recorded that Ibn `Abbas commented, "If it pleases you to know how ignorant the Arabs used to be, then recite the Ayat beyond Ayah one hundred and thirty in Surat Al-An`am,
قَدْ خَسِرَ الَّذِينَ قَتَلُواْ أَوْلَـدَهُمْ سَفَهاً بِغَيْرِ عِلْمٍ وَحَرَّمُواْ مَا رَزَقَهُمُ اللَّهُ افْتِرَآءً عَلَى اللَّهِ قَدْ ضَلُّواْ وَمَا كَانُواْ مُهْتَدِينَ
(Indeed lost are they who have killed their children, foolishly, without knowledge, and they have forbidden that which Allah has provided for them, inventing a lie against Allah. They have indeed gone astray and were not guided.)" Al-Bukhari also recorded this in the section of his Sahih on the virtues of the Quraysh.
المُيَسَّر
قد خسر وهلك الذين قتلوا أولادهم لضعف عقولهم وجهلهم، وحرموا ما رزقهم الله كذبًا على الله. قد بَعُدوا عن الحق، وما كانوا من أهل الهدى والرشاد. فالتحليل والتحريم من خصائص الألوهية في التشريع، والحلال ما أحله الله، والحرام ما حرَّمه الله، وليس لأحد من خَلْقه فردًا كان أو جماعة أن يشرع لعباده ما لم يأذن به الله.
