Jabir b. 'Abdullah reported Allah's Apostle ﷺ as saying: There is no transitive disease, no safar, no ghoul. He (the narrator) said: I heard Abu Zubair say: Jabir explained for them the word safar. Abu Zubair said: safar means belly. It was said to Jabir: Why is it so? He said that it was held that safar implied the worms of the belly, but he gave no explanation of ghoul. Abu Zubair said: Ghoul is that which kills the travellers.

وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ " لاَ عَدْوَى وَلاَ صَفَرَ وَلاَ غُولَ " . وَسَمِعْتُ أَبَا الزُّبَيْرِ يَذْكُرُ أَنَّ جَابِرًا فَسَّرَ لَهُمْ قَوْلَهُ " وَلاَ صَفَرَ " . فَقَالَ أَبُو الزُّبَيْرِ الصَّفَرُ الْبَطْنُ . فَقِيلَ لِجَابِرٍ كَيْفَ قَالَ كَانَ يُقَالُ دَوَابُّ الْبَطْنِ . قَالَ وَلَمْ يُفَسِّرِ الْغُولَ . قَالَ أَبُو الزُّبَيْرِ هَذِهِ الْغُولُ الَّتِي تَغَوَّلُ .
