Sunan an-Nasa'i, Hadith 3712 ⓘ
(A different chain) from Sufyan, from Abu Az-Zubair, from Tawus, from Ibn 'Abbas, who said: "Ruqba and 'Umra are not permissible; whoever is given something on the basis of 'Umra, it is his, and whoever is given something on the basis of Ruqba, it is his."
أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا يَعْلَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لاَ تَحِلُّ الرُّقْبَى وَلاَ الْعُمْرَى فَمَنْ أُعْمِرَ شَيْئًا فَهُوَ لَهُ وَمَنْ أُرْقِبَ شَيْئًا فَهُوَ لَهُ .
