(Muhammad) 47 : 9
ذَٰلِكَ بِأَنَّهُمْ كَرِهُوا مَا أَنْزَلَ اللَّهُ فَأَحْبَطَ أَعْمَالَهُمْ
That is because they hated what Allah revealed, so He made their deeds futile.
If Adhikr is not utilised as the Balance, all deeds become service to the disbeliever Satan. For any deed to be accepted by Allah, proof from Adhikr is required. For prayer to be answered and deeds to be accepted, two conditions are specified as explained in verse 2:186. See explanation 7:8-9; 18:103-105; and 43:74-78.
