عن أبي الدرداء رضي الله عنه عن النبي صلى الله عليه وسلم قال: «إِنَّ اللَّعَّانِين لا يَكُونُونَ شُفَعَاءَ، وَلا شُهَداءَ يَوْمَ القِيَامةِ».
[صحيح] - [رواه مسلم]

Abu Ad-Dardā' (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Those who indulge in cursing will not be intercessors or witnesses on the Day of Resurrection."
[Authentic hadith] - [Narrated by Muslim]
This Hadīth contains a warning against frequent cursing. Those who curse frequently have no place in the sight of Allah, nor is their intercession accepted in this world, because they are not considered upright while testimony is only accepted from upright people. Also their intercession or testimony is rejected in favor of their fellow Muslims to enter Paradise. Moreover, their testimony regarding the previous nations, that their messengers conveyed the message to them, is also not accepted.
