21- أَبَانٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ اللهِ عَنْ حُمْرَانَ قَالَ سَأَلْتُهُ عَنِ السُّكْنَى وَالْعُمْرَى فَقَالَ إِنَّ النَّاسَ فِيهِ عِنْدَ شُرُوطِهِمْ إِنْ كَانَ شَرَطَهُ حَيَاتَهُ سَكَنَ حَيَاتَهُ وَإِنْ كَانَ لِعَقِبِهِ فَهُوَ لِعَقِبِهِ كَمَا شَرَطَ حَتَّى يَفْنَوْا ثُمَّ يُرَدُّ إِلَى صَاحِبِ الدَّارِ.
21. Aban has narrated from ‘ Abd af-Rahman ibn abu ‘ Abd Aliah from Humran who has narrated the foifowing: “I once asked him (the Imam) (a.s.), about al-Sukna ’ and al^Umra’ (permission to use a house for a certain period of time). He (the Imam) said, ‘People must stand by their conditions. If his condition is permission to use the house for his life time, it then is for his life time. If it is for the life time of those whom he leaves behind, then it is for their life time after which they must return it to the owner of the house.’”
