النُّعْمَانَ بْنَ بَشِيرٍ، يَقُولُ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: الحَلاَلُ بَيِّنٌ، وَالحَرَامُ بَيِّنٌ، وَبَيْنَهُمَا مُشَبَّهَاتٌ لاَ يَعْلَمُهَا كَثِيرٌ مِنَ النَّاسِ (صحيح البخاري)
Nu’man ibn Bashir said he heard the Prophet ﷺ say, ‘The Halal is clear and the Haram is clear, and between them are ambiguous matters, most people do not know them.’ (Sahih al-Bukhari, 52).
The best way to persuade any Muslim regarding any religious issue is to quote and explain to them Quran and Hadith. As well as presenting the understanding classical scholars had regarding the Quranic verses or Hadith being presented. The above Hadith makes it clear that there are aspects of the Deen that have been left open to interpretation, and therefore open to difference of opinion.
With regards to this particular issue it is good to explain that difference of opinion in this Deen is by design, meaning Allah (Most High) decreed it. Nothing happens in the Deen of Allah (Most High) except by His planning and decision. It is truly clear to see in Hadith that the Prophet ﷺ made it unambiguous that he wanted room for difference of opinion.
The Prophet ﷺ wanted flexibility for the Ummah and when specific evidences and examples are given, hopefully, people should understand the issue well. One should also demonstrate for the listener how the Sahabah differed over many matters, and how the differences were respected.

And Allah (Most High) Knows Best.
