In my opinion, one of the most effective passages in the Bible to begin with when in evangelism with Muslims, is Mark 7:1-23. (especially Mark 7:14-23)
I would like to see a debate with Muslims that takes Mark 7:1-23 and explores:
1. Can external religious ritual washings (using physical water) cleanse the internal heart/soul from sin?
2. What is the root of human sin?
3. Where do sinful actions come from?
use also Jeremiah 17:9 and Genesis 6:5 and Jeremiah 13:23
4. Did we get sinful hearts and guilt from Adam?
5. Why do human beings always die?
Sam Shamoun believes that the texts of Islam actually do teach the doctrine of original sin (or something very close to it.)
Muslim scholars would likely disagree with his analysis, using Qur'an, Surah 30:30. Surah number 30 is called "Romans".
فَأَقِمْ وَجْهَكَ لِلدِّينِ حَنِيفًا ۚ فِطْرَتَ اللَّهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا ۚ لَا تَبْدِيلَ لِخَلْقِ اللَّهِ ۚ ذَٰلِكَ الدِّينُ الْقَيِّمُ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ
Sahih International"So direct your face toward the religion, inclining to truth. [Adhere to] the fitrah of Allah upon which He has created [all] people. No change should there be in the creation of Allah . That is the correct religion, but most of the people do not know."
Yusuf Ali translation:
" So set thou thy face steadily and truly to the Faith: (establish) Allah´s handiwork according to the pattern on which He has made mankind: no change (let there be) in the work (wrought) by Allah: that is the standard Religion: but most among mankind understand not."' See Surah 30 in Yusuf Ali translation.
This on-line translation is different than my own book copy of Yusuf Ali's translation of the Qur'an, so I assume that the translation committee has made an updated translation. My older Qur'an/book says, "nature, being upright" for Fitrah. The word "pattern" appears to be the new way they are translating Fitrah.
There are two different Arabic words that are translated as "religion" - حنیفا (Hanifeh - usually understood as "original monotheism" (of Abraham). In Islamic history, the people before Islam started who were searching for the true religion of Abraham, were known as the "Hanifeh".
The second one is "deen" (or Al-Deen", the religion, الدین ).
"fitrah" فطرت is also translated as "upright nature" or "nature".
But, Sam makes a good case for this, for some kind of teaching similar to the Christian doctrine of original sin, that is in the Islamic texts.
6. How do Muslims deal with the weight of all that evidence from both the Qur'an and Hadith?
7. How do Muslims explain this issue, without avoiding all those texts that Sam has provided, both from Hadith sources and the Qur'an?
