Please stop worrying about what people are doing and start looking for what Allah asks you to do.
Jews, Christians, and now 'muslims' are repeatedly told to follow ONLY WHAT Allah has revealed and we have His complete Message in the Qur'an. Anything else you want to do, cultural traditions are fine as long as they are not turned into 'islamic' religious obligations and this includes the ritual namaaz prayer. The Qur'an has no such thing, and salat in brief is to read, understand and then put in to practice the teachings of Allah; you can only do this by:-
5:44 We did send down the Torah containing guidance and a light. By it the Prophets who always sincerely submitted to God, judged the Jews. And the rabbis and the priests judged according to God’s Scripture as they were commanded to observe. To them was entrusted the protection of God’s Book, and they were witnesses to it. So, fear not people, but fear Me and do not trade away My revelations for petty gains. And whoever fails to judge or rule by what God has revealed, such are the disbelievers (‘Kafiroon’).
5:45 For them (Jews), We had decreed in the Torah: Life for life, eye for eye, nose for nose, ear for ear, tooth for tooth, and equal injury for injury. But if one forgoes retaliation by way of charity, it will absolve his imperfections. And whoever fails to judge or rule by what God has revealed, such are wrongdoers (‘Zalimoon’). [Exodus 21:23. That was a Mosaic laws specific to the Israelites. The Final revelation of God, the Qur’an has updated laws for all humanity for all times. Incidentally, Exodus in the Bible as seen today leaves no room for forgiveness of the mentioned offenses]
5:46 And after them We caused Jesus, son of Mary, to follow in their footsteps, confirming (the remaining truth in) what was revealed before him in Taurah. We gave him the Gospel in which there was guidance and a light, and it confirmed the (truth in) what was revealed before it in the Torah, a guidance and admonition to those who wished to live upright. [2:101, 3:78]
5:47 Let the People of the Gospel judge by what God has revealed therein. And whoever fails to judge or rule by what God has revealed, are drifters from the right path (‘Faasiqoon’).
5:48 (O Messenger) We have sent to you this Divine Writ, setting forth the truth. It confirms the remaining truth in the earlier Scriptures since it is a Watcher over them. So, judge between them by what God has revealed, and do not follow their desires diverging from the truth that has come to you. For each community among you We have appointed certain evolving trends and a traced-out way. If God had willed, He could have made you all one single community. But He decided to let you test yourselves by what (potentials) He has granted you. So, outdo one another in doing good to the society. To God you will all return, and He will then make you understand wherein you differed. [2:101, 2:148, 3:78, 21:92-93, 23:52. ‘Muhaimin’ = Watcher. ‘Shari’ah’ = Evolving trends of a community = Rites. ‘Minhaaj’ = A traced-out way = A set of laws. ‘min-al-kitab’ = From or remaining from the Scripture]
5:49 So judge between them by what God has revealed. And do not follow their vain desires. Beware of them, lest they divert you from some of what God has revealed to you. If they turn away from the truth, be assured that God has decided to chastise them for some of their crimes. A great many people drift away from the right path.
