"Habib bin Abi Thabit informed us from Ibn 'Umar, that the Messenger of Allah said: 'There is no 'Umra and no Ruqba. Whoever is given something on the basis of 'Umra or Ruqba, it belongs to him for the rest of his life and after he dies.'" (Using translation from Nasāʾī 3732)

أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ لَا عُمْرَى وَلَا رُقْبَى فَمَنْ أُعْمِرَ شَيْئًا أَوْ أُرْقِبَهُ فَهُوَ لَهُ حَيَاتَهُ وَمَمَاتَهُ
