Abdullah ibn al-Zubayr · The Book of Hajj

"The wife of sinan bin Salamah Al-Juhani ordered that the question be put to the Messenger of Allah about her mother who had died and had not performed Hajj; would it be good enough if she were to perform Hajj on behalf of her mother? He said: 'Yes. If her mother owed a debt and she paid it off, would that not be good enough? Let her perform Hajj on behalf of her mother.'''

"A man said: 'O Messenger of Allah! My father has died and he did not perform Hajj; shall I perform Hajj on his behalf?' He said: 'Don't you think that if your father owed a debt you would pay it off?' The man said: 'Yes.' He said: 'The debt owed to Allah is more deserving (of being paid off)."'

the Messenger of Allah used to dismount at Dhu Tuwa and stay there overnight unitl he prayed Subh when he was approaching Makkah. The place where the Messenger of Allah prayed was on top of the big hillock and not in the Masjid that was built later on, but it was lower than that, on top of the big hillock.

"The Messenger of Allah said: 'The Kabah will be destroyed by Dhul-Suwaiqatan (one with thin legs) from Ethiopia.'"
