(regarding the Verse): 'If any of you dies and leaves wives behind,' That was the period of the 'Iddah
which the widow was obliged to spend in the house of the late husband. Then Allah revealed: And
those of you who die and leave wives should bequeath for their wives a year's maintenance and
residence without turning them out, but if they leave, there is no blame on you for what they do of
themselves, provided it is honorable (i.e. lawful marriage) (2.240) Mujahid said: Allah has ordered
that a widow has the right to stay for seven months and twenty days with her husband's relatives
through her husband's will and testament so that she will complete the period of one year (of 'Iddah).
But the widow has the right to stay that extra period or go out of her husband's house as is indicated
by the statement of Allah: 'But if they leave there is no blame on you,... ' (2.240) Ibn `Abbas said: The
above Verse has cancelled the order of spending the period of the 'Iddah at her late husband's house,
and so she could spend her period of the 'Iddah wherever she likes. And Allah says: 'Without turning
them out.' 'Ata said: If she would, she could spend her period of the 'Iddah at her husband's house, and
live there according to her (husband's) will and testament, and if she would, she could go out (of her
husband's house) as Allah says: 'There is no blame on you for what they do of themselves.' (2.240)
'Ata added: Then the Verses of inheritance were revealed and the order of residence (for the widow)
was cancelled, and she could spend her period of the 'Iddah wherever she would like, and she was no
longer entitled to be accommodated by her husband's family.
Sahih al-Bukhari Book 68, Hadith 89
that Malik bin Aus said, "I was in need of change for one-hundred Dinars. Talha bin 'Ubaidullah
called me and we discussed the matter, and he agreed to change (my Dinars). He took the gold pieces
in his hands and fidgeted with them, and then said, "Wait till my storekeeper comes from the forest."
`Umar was listening to that and said, "By Allah! You should not separate from Talha till you get the
money from him, for Allah's Messenger (ﷺ) said, 'The selling of gold for gold is Riba (usury) except if the
exchange is from hand to hand and equal in amount, and similarly, the selling of wheat for wheat is
Riba (usury) unless it is from hand to hand and equal in amount, and the selling of barley for barley is
usury unless it is from hand to hand and equal in amount, and dates for dates, is usury unless it is from
hand to hand and equal in amount"
