"The Messenger of Allah said: 'Umra (life-long gift) is permissible for the one to whom it is given, and Ruqba is permissible to the one to whom it is given, and the one who takes back his gift is like the one who goes back to his vomit
أَخْبَرَنَا أَحْمَدُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ حَجَّاجٍ، عَنْ أَبِي الزُّبَيْرِ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ الْعُمْرَى جَائِزَةٌ لِمَنْ أُعْمِرَهَا وَالرُّقْبَى جَائِزَةٌ لِمَنْ أُرْقِبَهَا وَالْعَائِدُ فِي هِبَتِهِ كَالْعَائِدِ فِي قَيْئِهِ ‏"‏ ‏.‏
