وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ تَعَلَّمَ صَرْفَ الْكَلَامِ لِيَسْبِيَ بِهِ قُلُوبَ الرِّجَالِ أَوِ النَّاسِ لَمْ يَقْبَلِ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ صَرْفًا وَلَا عدلا» . رَوَاهُ أَبُو دَاوُد
Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever learns speech only so that he may, through it, gain control over the hearts of men or people, then on the Day of Resurrection, Allah will not accept any voluntary or obligatory act of worship from him." Its chain is weak, narrated by Abu Dawood.
