abudawud:3915Muḥammad b. al-Muṣaffá > Baqiyyah > Limuḥammad / Ibn Rāshid Qawluh Hām > Kānat al-Jāhiliyyah

I asked Muhammad b. Rashid about the meaning of the word hamah. He replied: The pre-Islamic Arabs used to say: When anyone dies and is buried, a bird comes forth from his grave. I asked: What did he mean by safar ? He said: I heard that the pre-Islamic Arabs used to take evil omen from safar. So the Prophet ﷺ said: There is no safar. Muhammad (b. Rashid) said: We heard someone say: It is a pain in the stomach. They said that it was infection. Hence he said: There is no safar.  

أبو داود:٣٩١٥حَدَّثَنَا مُحَمَّدُ بْنُ الْمُصَفَّى حَدَّثَنَا بَقِيَّةُ قَالَ قُلْتُ لِمُحَمَّدٍ يَعْنِي ابْنَ رَاشِدٍ قَوْلُهُ هَامَ قَالَ

كَانَتِ الْجَاهِلِيَّةُ تَقُولُ لَيْسَ أَحَدٌ يَمُوتُ فَيُدْفَنُ إِلاَّ خَرَجَ مِنْ قَبْرِهِ هَامَةٌ قُلْتُ فَقَوْلُهُ صَفَرَ قَالَ سَمِعْتُ أَنَّ أَهْلَ الْجَاهِلِيَّةِ يَسْتَشْئِمُونَ بِصَفَرَ فَقَالَ النَّبِيُّ ﷺ لاَ صَفَرَ قَالَ مُحَمَّدٌ وَقَدْ سَمِعْنَا مَنْ يَقُولُ هُوَ وَجَعٌ يَأْخُذُ فِي الْبَطْنِ فَكَانُوا يَقُولُونَ هُوَ يُعْدِي فَقَالَ لاَ صَفَرَ
