The Prophet ﷺ as saying: Life tenancy is permissible.  

عَنِ النَّبِيِّ ﷺ قَالَ الْعُمْرَى جَائِزَةٌ  

A similar tradition has also been transmitted by Samurah from the Prophet ﷺ through a different chain of narrators.  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ  

The Prophet ﷺ has saying: What is given in life-tenancy belongs to the one to whom it was given.  

أَنَّ نَبِيَّ اللَّهِ ﷺ كَانَ يَقُولُ الْعُمْرَى لِمَنْ وُهِبَتْ لَهُ  

The Prophet ﷺ said: If anyone is given life-tenancy, it belongs to him and to his descendants. His descendants who inherit him will inherit from it.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أُعْمِرَ عُمْرَى فَهِيَ لَهُ وَلِعَقِبِهِ يَرِثُهَا مَنْ يَرِثُهُ مِنْ عَقِبِهِ  

A similar tradition has also been transmitted by al-Laith b. Sa'd from al-Zuhri, from Abu Salamah from Jabir.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ
