When you are advising others and not doing it
Described as greatly hated in the sight of Allah.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لِمَ تَقُولُونَ مَا لَا تَفْعَلُونَ كَبُرَ مَقْتًا عِندَ ٱللَّهِ أَن تَقُولُوا۟ مَا لَا تَفْعَلُونَ
Yā ayyuha-lladhīna āmanū lima taqūlūna mā lā tafʿalūn, kabura maqtan ʿinda-llāhi an taqūlū mā lā tafʿalūn.
“O you who have believed, why do you say what you do not do? Greatly hateful in the sight of Allāh is that you say what you do not do.”
