Abu Sa'id al-Khudri (RAA), narrated that the Messenger of Allah (ﷺ) said:

“There are two characteristics which are not combined in a believer; miserliness and bad morals.” Related by At-Tirmidhi with a weakness in its chain of narrators.

وَعَنْ أَبِي سَعِيدٍ اَلْخُدْرِيِّ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ خَصْلَتَانِ لَا يَجْتَمِعَانِ فِي مُؤْمِنٍ: اَلْبُخْلُ, وَسُوءُ اَلْخُلُقِ } أَخْرَجَهُ اَلتِّرْمِذِيُّ, وَفِي سَنَدِهِ ضَعْفٌ.‏ [1]‏ .‏
