A hadlth like this has been transmitted on the authority of Ibn Shibab who said that they (the Compnions of the Holy Prophet) followed the latest of his commands and looked upon it as one abrogating (the previous ones) and the most firm.
ابْنُ شِهَابٍ فَكَانُوا يَتَّبِعُونَ الأَحْدَثَ فَالأَحْدَثَ مِنْ أَمْرِهِ وَيَرَوْنَهُ النَّاسِخَ الْمُحْكَمَ
