عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا اسْتَرَاثَ الْخَبَرَ تَمَثَّلَ فِيهِ بِبَيْتِ طَرَفَةَ وَيَأْتِيكَ بِالْأَخْبَارِ مَنْ لَمْ تُزَوِّدْ
It is narrated from Sayyida Aisha (may Allah be pleased with her), she states that when there was a delay in receiving news, the Prophet would recite this verse of the poet Tarafah (bin Abd Bakri): "Wa ya'teeka bil-akhbaari man lam tuzawwid" (The person will bring you news whom you did not provide anything for).
