There Is No 'Adwa, No Tiyarah (Evil Omens), No Hamah. No Safar, No Nawa', And No Ghoul, And No Sick Camel Should Be Brought To A Healthy Camel
Sahih Muslim
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم 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 .
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.
