Yahya related to me from Malik from Ibn Shihab from Salim ibn
Abdullah that Abdullah ibn Muhammad ibn Abi Bakras-Siddiq told
Abdullah ibn Umar from A'isha, that the Prophet, may Allah bless him
and grant him peace, said, "Don't you see that when your people built
the Kaba they fell short of the foundations of Ibrahim?" A'isha said,
"Messenger of Allah, won't you return it to the foundations of
Ibrahim?" and the Messenger of Allah, may Allah bless him and grant
him peace, said, "If it were not that your people have only recently
left kufr, I would have done so."
Salim ibn Abdullah said
that Abdullah ibn Umar said, "If A'isha heard this from the Messenger
of Allah, may Allah bless him and grant him peace, then I consider
that the Messenger of Allah, may Allah bless him and grant him peace,
only refrained from greeting the two corners which are adjacent to the
Hijr because the House had not been completed on the foundations of
Ibrahim." (i.e. the corners he did not touch were not the original
corners of the Kaba) .
Muwatta Malik Book 20, Hadith 108
"Ibn 'Awn narrated to us, from Nafi', from Ibn 'Umar, from 'Umar, who said: 'I acquired some land at Khaibar. He came to the Prophet and said: I have acquired some land at Khaibar, and I have never been given any wealth that is more precious to me than it. What do you command me to do with it? He said: If you wish, you can 'freeze' it and give it in charity. So he gave it in charity on condition that it would not be sold, given away or inherited, to the poor, relatives, slaves, for the cause of Allah, guests and wayfarers. There is no sin on the one who administers it if he eats from it on a reasonable basis and feeds his friend, with no intention of becoming wealthy from it.'"
