NASAI 3708:
from Ibn ʿAbbās —
"Abdul-Jabbar bin Al-'Ala' narrated to us, he said: 'Sufyan narrated to us from Ibn Abi Najih, from Tawus, and perhaps it is from Ibn 'Abbas, who said: There is no Ruqba, and whoever gives a gift on the basis of Ruqba, it is part of his estate.'"
النسائي ٣٧٠٨:
عن ابن عباس —
لاَ رُقْبَى فَمَنْ أُرْقِبَ شَيْئًا فَهُوَ سَبِيلُ الْمِيرَاثِ
