sahih· Al-Albani

Bakr ibn 'Abdullah reported that the Companions of the Prophet, (ﷺ), used to throw melons at one another. He said, "If these were real, they would be men."

حَدَّثَنَا صَدَقَةُ، قَالَ‏:‏ أَخْبَرَنَا مُعْتَمِرٌ، عَنْ حَبِيبٍ أَبِي مُحَمَّدٍ، عَنْ بَكْرِ بْنِ عَبْدِ اللهِ قَالَ‏:‏ كَانَ أَصْحَابُ النَّبِيِّ صلى الله عليه وسلم يَتَبَادَحُونَ بِالْبِطِّيخِ، فَإِذَا كَانَتِ الْحَقَائِقُ كَانُوا هُمُ الرِّجَالَ‏.‏
