Hojat-ol-Islam Syed Ali Raza Rizvi, speaking in a series on Islamic lifestyle, referred to verse 3 of Surah As-Saff (61) “It is most hateful in the sight of God if you preach something and do not practice it yourself”, and underlined the need for everyone not to advise others to do something while they themselves act differently.
Allah very much dislikes preaching what one does not practice, he said.
