عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((هَذِهِ عُمْرَةٌ اسْتَمْتَعْنَا بِهَا، فَمَنْ لَمْ يَكُنْ مَعَهُ هَدْيٌ فَلْيَحِلِّ الْحِلَّ كُلَّهُ، فَقَدْ دَخَلَتِ الْعُمْرَةُ فِي الْحَجِّ إِلَى يَوْمِ الْقِيَامَةِ))
Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): The Noble Prophet (peace and blessings be upon him and his family) said: We are benefiting from this ‘Umrah; those who do not have a sacrificial animal with them should become completely halal (i.e., come out of the state of ihram). Until the Day of Judgment, ‘Umrah has been included in Hajj (i.e., ‘Umrah can be performed during the months of Hajj until the Day of Judgment).
