Sunan of Abu Dawood Book 21, Hadith 3180

حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، عَنْ خَالِدٍ، عَنْ يُونُسَ، عَنْ زِيَادِ بْنِ جُبَيْرٍ، عَنْ أَبِيهِ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، - وَأَحْسَبُ أَنَّ أَهْلَ، زِيَادٍ أَخْبَرُونِي أَنَّهُ، رَفَعَهُ إِلَى النَّبِيِّ صلى الله عليه وسلم - قَالَ ‏ "‏ الرَّاكِبُ يَسِيرُ خَلْفَ الْجَنَازَةِ وَالْمَاشِي يَمْشِي خَلْفَهَا وَأَمَامَهَا وَعَنْ يَمِينِهَا وَعَنْ يَسَارِهَا قَرِيبًا مِنْهَا وَالسِّقْطُ يُصَلَّى عَلَيْهِ وَيُدْعَى لِوَالِدَيْهِ بِالْمَغْفِرَةِ وَالرَّحْمَةِ ‏"‏ ‏.‏

Prayer should be offered over an abortion and forgiveness and mercy supplicated for its parents
