Hadith 16:62
Ibn ’Abbas (RAA) narrated that the Messenger of Allah (ﷺ) said:
“Don’t dispute with your brother; don’t make jokes with him; and don’t make him a promise which you would break.” Related by At-Tirmidhi with a weak chain of narrators.
وَعَنْ اِبْنِ عَبَّاسٍ -رَضِيَ اَللَّهُ عَنْهُمَا- قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَا تُمَارِ أَخَاكَ, وَلَا تُمَازِحْهُ, وَلَا تَعِدْهُ مَوْعِدًا فَتُخْلِفَهُ } أَخْرَجَهُ اَلتِّرْمِذِيُّ بِسَنَدٍ فِيهِ ضَعْفٌ
