There would be no harm if you do not (proceed) for Hajj this year, for we fear that there would be fight among people which would cause obstruction between you and the House, whereupon he said: If there would be obstruction between me and that (Ka'ba), I would do as Allah's Messenger (ﷺ) did. I was with him (the Holy Prophet) when the infidels of Quraish caused obstructions between him (the Holy Prophet) and the House. I call you as my witness (to the fact) that I have made 'Umra essential for me. He proceeded until he came to Dhu'l-Hulaifa and pronounced Talbiya for Umra, and said: If the way Is clear forme, I would then complete my 'Umra but If there is some obstruction between me and that (the Ka'ba). I would then do what Allah's Messenger (ﷺ) had done (at the occasion of Hudaibiya), and I was with him (the Holy Prophet). and then recited:" Verily in the Messenger of Allah, there is a model pattern for you" (xxxiii. 21). He then moved on until he came to the rear side of al-Baida' and said: There is one command for both of them automatically) (Hajj and Umra). If I am detained (in the performance) of 'Umra, I am ( automatically detained (in the performance) of Hajj (too). I call you as witness that Hajj along with 'Umra I had made essential for me. (I am performing Hajj and 'Umra as Qiran.) He then bought sacrificial animals at Qudaid and then circumambulated the House and ran between al-Safa' and al-Marwa once (covering both Hajj and Umra), and did not put off Ihram until on the Day of Sacrifice in the month of Dhu'l-Hijja.
Sahih Muslim Book 15, Hadith 198
While I was with Aisha, the mother of the Believers, a person from Iraq came and asked, "What type
of shroud is the best?" `Aisha said, "May Allah be merciful to you! What does it matter?" He said, "O
mother of the Believers! Show me (the copy of) your Quran," She said, "Why?" He said, "In order to
compile and arrange the Quran according to it, for people recite it with its Suras not in proper order."
`Aisha said, "What does it matter which part of it you read first? (Be informed) that the first thing that
was revealed thereof was a Sura from Al-Mufassal, and in it was mentioned Paradise and the Fire.
When the people embraced Islam, the Verses regarding legal and illegal things were revealed. If the
first thing to be revealed was: 'Do not drink alcoholic drinks.' people would have said, 'We will never
leave alcoholic drinks,' and if there had been revealed, 'Do not commit illegal sexual intercourse, 'they
would have said, 'We will never give up illegal sexual intercourse.' While I was a young girl of
playing age, the following Verse was revealed in Mecca to Muhammad: 'Nay! But the Hour is their
appointed time (for their full recompense), and the Hour will be more grievous and more bitter.'
(54.46) Sura Al-Baqara (The Cow) and Surat An-Nisa (The Women) were revealed while I was with
him." Then `Aisha took out the copy of the Quran for the man and dictated to him the Verses of the
Suras (in their proper order) .
Sahih al-Bukhari Book 66, Hadith 15
Malik said, "Another example of that is that the Messenger of
Allah, may Allah bless him and grant him peace, forbade the sale
called muzabana and granted an indulgence in the ariya for computing
the equivalent in dates. It was distinguished between them that the
muzabana-sale was based on shrewdness and trade, and the ariya sale
was based on a favour rendered, and there was no shrewdness in it."
Malik said, "A man must not buy food for a fourth, a third,
or a fraction of a dirham on the basis that he be given that food on
credit. There is no harm in a man buying food for a fraction of a
dirham on credit and then he gives a dirham and takes goods with what
remains of his dirham because he gave the fraction he owed as silver,
and took goods to make up the rest of his dirham. There is no harm in
that transaction."
Malik said, "There is no harm in a man
placing a dirham with another man and then taking from him known goods
for a fourth, third, or a known fraction. If there was not a known
price on the goods and the man said, 'I will take them from you for
the price of each day,' this is not halal because there is
uncertainty. It might be less one time, and more another time, and
they would not part with a known sale."
Malik said, "If
someone sells some food without measuring precisely and does not
exclude any of it from the sale and then it occurs to him to buy some
of it, it is not good for him to buy any of it except what it would be
permitted for him to exclude from it. That is a third or less. If it
is more than a third, it becomes muzabana and is disapproved. He must
only purchase from what he would be permitted to exclude, and he is
only permitted to exclude a third or less than that. This is the way
of doing things in which there is no dispute with us."
