Nafi' says that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) inherited the house of Sayyidah Hafsah bint Umar (may Allah be pleased with her). Sayyidah Hafsah (may Allah be pleased with her) had let the daughter of Zayd bin al-Khattab live in it for as long as she lived. When the daughter of Zayd died, Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) took the house and considered it his. This is reported concerning a loan ('ariyah), not an 'umra; and Allah knows best.
