So there did not die anyone in Makkah during those ten years...

وَ تَصْدِيقُ ذَلِكَ أَنَّ اللَّهَ عَزَّ وَ جَلَّ أَنْزَلَ عَلَيْهِ فِي سُورَةِ بَنِي إِسْرَائِيلَ بِمَكَّةَ وَ قَضى رَبُّكَ أَلَّا تَعْبُدُوا إِلَّا إِيَّاهُ وَ بِالْوالِدَيْنِ إِحْساناً إِلَى قَوْلِهِ تَعَالَى إِنَّهُ كانَ بِعِبادِهِ خَبِيراً بَصِيراً And the ratification of that is that Allah -azwj Mighty and Majestic Revealed unto him -saww in Surah Bani Israil (Chapter 17) in Makkah [17:23] And your Lord has Decreed that you shall not worship except Him, and goodness to the parents – up to His -azwj Words [17:30] He was always most Informed, All-Seeing of His servants .

أَدَبٌ وَ عِظَةٌ وَ تَعْلِيمٌ وَ نَهْيٌ خَفِيفٌ وَ لَمْ يَعِدْ عَلَيْهِ وَ لَمْ يَتَوَاعَدْ عَلَى اجْتِرَاحِ شَيْ‏ءٍ مِمَّا نَهَى عَنْهُ وَ أَنْزَلَ نَهْياً عَنْ أَشْيَاءَ حَذَّرَ عَلَيْهَا وَ لَمْ يُغَلِّظْ فِيهَا وَ لَمْ يَتَوَاعَدْ عَلَيْهَا وَ قَالَ وَ لا تَقْتُلُوا أَوْلادَكُمْ خَشْيَةَ إِمْلاقٍ نَحْنُ نَرْزُقُهُمْ وَ إِيَّاكُمْ إِنَّ قَتْلَهُمْ كانَ خِطْأً كَبِيراً وَ لا تَقْرَبُوا الزِّنى إِنَّهُ كانَ فاحِشَةً وَ ساءَ سَبِيلًا Discipline, and preaching, and teaching, and light Prohibitions, and He -azwj did not Threaten upon it and did not Threaten upon the audacity of anything from what He -azwj had Forbidden from, and He -azwj Sent down the Prohibition about things Cautioning upon it and was not Tough regarding these, and did not Threaten upon these, and Said [17:31] And do not kill your children for fear of poverty; We Give Sustenance to them and to yourselves; and beware!
