It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: Night-time storytelling and conversation (samar) came to be disliked when this verse was revealed: "In arrogance regarding it, conversing by night, speaking evil" [Surah al-Mu'minun: 67] . He said: They were arrogant on account of the House of Allah, saying: We are its custodians. And tahjurun means that they used to abandon it and did not keep it populated (with worship). The chain of narration of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
