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.

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