Hadith 34:12
Sahih (Darussalam)
'Abdul-Malik bin Abi Sulaiman narrated from 'Ata' who said:
"The Messenger of Allah said: 'Whoever is given something for the rest of his life, it belongs to him for as long as he lives and after he dies.'"
أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمٍ، قَالَ أَنْبَأَنَا حِبَّانُ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي سُلَيْمَانَ، عَنْ عَطَاءٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أُعْطِيَ شَيْئًا حَيَاتَهُ فَهُوَ لَهُ حَيَاتَهُ وَمَوْتَهُ "
