عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((لَا يُؤْمِنُ الْعَبْدُ الْإِيمَانَ كُلَّهُ حَتَّى يَتْرُكَ الْكَذِبَ مِنَ الْمُزَاحَةِ وَيَتْرُكَ الْمِرَاءَ وَإِنْ كَانَ صَادِقًا))
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: A person cannot attain complete faith until he gives up lying in jest and quarreling, even if he is truthful in that quarrel.
