Ibn ‘Abbas reported the Prophet (ﷺ) as saying This is an ‘Umrah from which we have benefitted. Anyone who has brought sacrificial animal with him should take off ihram totally. ‘Umrah has been included in Hajj till the Day of Judgment. Abu Dawud said This is a munkar (uncommon) tradition. This is in fact the statement of Ibn ‘Abbas himself.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، أَنَّ مُحَمَّدَ بْنَ جَعْفَرٍ، حَدَّثَهُمْ عَنْ شُعْبَةَ، عَنِ الْحَكَمِ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ ‏

‏ هَذِهِ عُمْرَةٌ اسْتَمْتَعْنَا بِهَا فَمَنْ لَمْ يَكُنْ عِنْدَهُ هَدْىٌ فَلْيَحِلَّ الْحِلَّ كُلَّهُ وَقَدْ دَخَلَتِ الْعُمْرَةُ فِي الْحَجِّ إِلَى يَوْمِ الْقِيَامَةِ ‏

‏ ‏.‏ قَالَ أَبُو دَاوُدَ هَذَا مُنْكَرٌ إِنَّمَا هُوَ قَوْلُ ابْنِ عَبَّاسٍ ‏.‏
