কানাঘুষা তো শয়তানের কাজ।

إِنَّمَا النَّجْوَىٰ مِنَ الشَّيْطَانِ لِيَحْزُنَ الَّذِينَ آمَنُوا وَلَيْسَ بِضَارِّهِمْ شَيْئًا إِلَّا بِإِذْنِ اللَّهِ ۚ وَعَلَى اللَّهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ
Secret counsels are only (inspired) by the Evil One, in order that he may cause grief to the Believers; but he cannot harm them in the least, except as Allah permits; and on Allah let the Believers put their trust. Surah Mujadila Ayat 10
