In the name of Allah, the Most Gracious, the Most Merciful.
Quran: Chapter 5 ‘Wal Muhsanaat’, Sura: 4 ‘An-Nisa’ ‘The Women’,
Verse 59: O you who believe! Obey Allah and obey the Messenger (Muhammad peace be upon him), and those of you (Muslims) who are in authority. (And) if you differ in anything amongst yourselves, refer it to Allah and His Messenger (peace be upon him), if you believe in Allah and in the Last Day. That is better and more suitable for final determination.
Notes by samia2010oct: If any one obeys what is in the Quran but does not obey the Traditions of Last Prophet Muhammad peace be upon him, he commits Gunaah e Kabira, Big Sin. If any one obeys the Traditions of Last Prophet Muhammad peace be upon him but does not obey the Quran, he also commits Gunaah e Kabira, Big Sin. For Big Sins there is the punishment of unbearable burning of whole body by Unending Fire.
