The Book of the Prohibited actions
Prohibition of Cursing one Particular Man or Animal
وَعَنْ أَبِي الدَّرْدَاءِ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : لاَ يَكُونُ اللَّعَّانُونَ شُفَعَاءَ، وَلاَ شُهَدَاءَ يَوْمَ الْقِيَامَةِ ((رَوَاهُ مُسْلِم)).
Abud-Darda' (May Allah be pleased with him) said: The Messenger of Allah (ﷺ) said, "Those who frequently resort to cursing (people) would neither be accepted as witnesses nor as intercessors on the Day of Resurrection." [Muslim].
