Yahya related to me from Malik that he had heard some of the
people of knowledge say, "If someone goes into ihram to do umra and
then wants to go into ihram to do hajj as well, he can do so, as long
as he has not done tawaf of the House and s'ay between Safa and Marwa.
This is what Abdullah ibn 'Umar did when he said, 'If I am blocked
from the House we shall do what we did when we were with the Messenger
of Allah, may Allah bless him and grant him peace.' He then turned to
his companions and said, 'It is the same either way. I call you to
witness that I have decided in favour of hajj and umra together. ' "
Malik said, "The companions of the Messenger of Allah, may
Allah bless him and grant him peace, went into ihram to do umra in the
year of the farewell hajj, and the Messenger of Allah, may Allah bless
him and grant him peace, said to them, 'Anyone that has a sacrificial
animal with him should go into ihram to do hajj and umra together, and
he should not come out of ihram until he has finished both.' "
Muwatta Malik Book 20, Hadith 43
A man expressed his intention to give charity, so he came out with charity and placed it in the hand of an adulteress. In the morning, the people were talking and saying: charity was given to an adulteress last night. He (the giver of Sadaqa) said: 0 Allah, to Thee be the praise-to an adulteress. He then again expressed his intention to give charity; so he went out with the charity and placed it in the hand of a rich person. In the morning the people were talking and saying: Charity was given to a rich person. He (the giver of charity) said: 0 Allah, to Thee be the praise-to a well-to-do person. He then expressed his intention to give charity, so he went out with charity and placed it in the hand of a thief. In the morning, the people were talking and saying: Charity was given to a thief. So (one of the persons) said: 0 Allah, to Thee be the praise (what a misfortune it is that charity has been given to) the adulteress, to a rich person. to a thief! There came (the angel to him) and he was told: Your charity has been accepted. As for the adulteress (the charity might become the means) whereby she might restrain herself from fornication. The rich man might perhaps learn a lesson and spend from what Allah has given him, and the thief might thereby refrain from committing theft.
