عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ أُتِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِجُبْنَةٍ فِي غَزَاةٍ فَقَالَ أَيْنَ صُنِعَتْ هَذِهِ فَقَالُوا بِفَارِسَ وَنَحْنُ نُرَى أَنَّهُ يُجْعَلُ فِيهَا مَيْتَةٌ فَقَالَ اطْعَنُوا فِيهَا بِالسِّكِّينِ وَاذْكُرُوا اسْمَ اللَّهِ وَكُلُوا ذَكَرَهُ شَرِيكٌ مَرَّةً أُخْرَى فَزَادَ فِيهِ فَجَعَلُوا يَضْرِبُونَهَا بِالْعِصِيِّ
Syedna Ibn Abbas (may Allah be pleased with them) narrates that during a battle, cheese was presented before the Noble Prophet (peace and blessings be upon him). He (peace be upon him) asked: "Where was this prepared?" They said: "It was prepared in the region of Persia, and we think that carrion meat is added to it." He (peace be upon him) said: "Cut it with a knife and eat it after reciting Bismillah." The second time when Shareek narrated this, he added: "People began to cut it with the sharp edge of their staffs."
