abudawud:3211 – ʿUbaydullāh b. Muʿādh from my father > Shuʿbah > Abū Isḥāq > Awṣá al-Ḥārith > Yuṣallī ʿAlayh ʿAbdullāh b. Yazīd Faṣallá ʿAlayh Thum Adkhalah al-Qabr from Qibal Rijla al-Qabr

Al-Harith left his will that Abdullah ibn Yazid should offer his funeral prayer; so he prayed over him. He then put him in the grave from the side of his legs and said: This is a Sunnah (model practice of the Prophet).  

أبو داود:٣٢١١ – حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ حَدَّثَنَا أَبِي حَدَّثَنَا شُعْبَةُ عَنْ أَبِي إِسْحَاقَ قَالَ أَوْصَى الْحَارِثُ أَنْ يُصَلِّيَ عَلَيْهِ عَبْدُ اللَّهِ بْنُ يَزِيدَ فَصَلَّى عَلَيْهِ ثُمَّ أَدْخَلَهُ الْقَبْرَ مِنْ قِبَلِ رِجْلَىِ الْقَبْرِ

وَقَالَ هَذَا مِنَ السُّنَّةِ
