Covering Corpse with Saliva

حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، سَمِعَ جَابِرًا ـ رضى الله عنه ـ قَالَ أَتَى النَّبِيُّ صلى الله عليه وسلم عَبْدَ اللَّهِ بْنَ أُبَىٍّ بَعْدَ مَا دُفِنَ فَأَخْرَجَهُ، فَنَفَثَ فِيهِ مِنْ رِيقِهِ وَأَلْبَسَهُ قَمِيصَهُ‏.‏

Narrated Jabir: The Prophet (ﷺ) came to (the grave of) `Abdullah bin Ubai after his body was buried. The body was brought out and then the Prophet (ﷺ) put his saliva over the body and clothed it in his shirt.
