Salaamun Alaikum Dear Br Joseph,
Almost always whenever I speak with family and friends about studying and upholding Qur'an, as it's complete, fully detailed and purging their hearsay conjectures, their first response is if the Qur'an is complete then show us where it's written in the Qur'an about how to pray Salaat.
My response usually is that Almost All religious orders (Salaat, Haj, Fasting, etc) came through the original founder of Islam, i.e Prophet Ibraheem (PBUH) and
Prophet Muhammed (PUBH) was instructed to follow the religion of Ibraheem (PBUH) and it makes sense that religious practices were existed and known to the Arabs at the time of Prophet Muhammed (PBUH).
In addition, Qiyaam, Ruku, Sujood is mentioned in the Qur'an and that Hadiths also do not contain full details about Salaat except few references here and there.
I also say that most Muslims perform Salaat based on their sect and the way they found their parents/community doing and NOT what the Hadiths have to say.
Infact, it's just an argument people use to support Hadiths and to reject Qur'an without perceiving what exactly they are saying and doing.
I also argue that even if it was written in the Qur'an people would still perform the prayers the way they found their parents/community doing.
I often cite example of Wudu, divorce, punishment for adultery, first Kalima etc. Despite the fact that these are mentioned in the Qur'an with full details, people still do not follow the Qur'an.
Infact, most people do not Read neither Ahadiths nor Qur'an. Violating Qur'an's numerous commandments including Reading, Studying, Pondering, Discussing and Seeking Knowledge.
How do you answer encounter these stereotype questions like how to perform Salaat in the Qur'an.
May Allah (SWT) bless you and reward you for all the good work you do, IA.
Best regards,
