يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَطِيعُوا۟ ٱللَّهَ وَأَطِيعُوا۟ ٱلرَّسُولَ وَأُو۟لِى ٱلْأَمْرِ مِنكُمْ ۖ فَإِن تَنَٰزَعْتُمْ فِى شَىْءٍۢ فَرُدُّوهُ إِلَى ٱللَّهِ وَٱلرَّسُولِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۚ ذَٰلِكَ خَيْرٌۭ وَأَحْسَنُ تَأْوِيلًا
O ye who believe! Obey Allah, and obey the messenger and those of you who are in authority; and if ye have a dispute concerning any matter, refer it to Allah and the messenger if ye are (in truth) believers in Allah and the Last Day. That is better and more seemly in the end.
Surah An-Nisaa(4:59)
Sahih al-Bukhari
Call to Prayers (Adhaan)
Chapter: Saying the Takbir on raising from the prostration
Narrated `Ikrima:
I prayed behind a Sheikh at Mecca and he said twenty two Takbirs (during the prayer). I told Ibn `Abbas that he (i.e. that Sheikh) was foolish. Ibn `Abbas admonished me and said, "This is the tradition of Abul-Qasim."
