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 ‏"‏ هَذِهِعُمْرَةٌ 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
Translation

Uthman bin Abi Shaybah narrated to us, that Muhammad bin Ja'far narrated to them, from Shu'bah, from al-Hakam, from Mujahid, from Ibn 'Abbas, from the Prophet (ﷺ) that he said: "This is an 'Umrah from which we have benefited. Whoever does not have a sacrificial animal with him, let him exit Ihram completely, for 'Umrah has entered into Hajj until the Day of Resurrection." Abu Dawud said: This is munkar (rejected); it is merely the statement of Ibn 'Abbas.
