I saw Allah's Messenger (ﷺ) on the day (of the battle) of the Trench carrying earth till the hair of his chest
were covered with dust and he was a hairy man. He was reciting the following verses of `Abdullah
(bin Rawaha): "O Allah, were it not for You, We would not have been guided, Nor would we have
given in charity, nor prayed. So, bestow on us calmness, and when we meet the enemy. Then make
our feet firm, for indeed, Yet if they want to put us in affliction, (i.e. want to fight against us) we
would not (flee but withstand them)." The Prophet (ﷺ) used to raise his voice while reciting these verses.
(See Hadith No. 432, Vol. 5).
Sahih al-Bukhari Book 56, Hadith 241
`Urwa said, "Aisha told me that Allah's Messenger (ﷺ) used to examine the women
emigrants. We have been told also that when Allah revealed the order that the Muslims should return
to the pagans what they had spent on their wives who emigrated (after embracing Islam) and that the
Muslims should not keep unbelieving women as their wives, `Umar divorced two of his wives,
Qariba, the daughter of Abu Umayyah and the daughter of Jarwal Al-Khuza`i. Later on Mu`awiya
married Qariba and Abu Jahm married the other."
When the pagans refused to pay what the Muslims had spent on their wives, Allah revealed: "And if
any of your wives have gone from you to the unbelievers and you have an accession (by the coming
over of a woman from the other side) (then pay to those whose wives have gone) the equivalent of
what they had spent (on their Mahr)." (60.11)
So, Allah ordered that the Muslim whose wife has gone, should be given, as a compensation of the
Mahr he had given to his wife, from the Mahr of the wives of the pagans who had emigrated deserting
their husbands.
We do not know any of the women emigrants who deserted Islam after embracing it. We have also
been told that Abu Basir bin Asid Ath-Thaqafi came to the Prophet (ﷺ) as a Muslim emigrant during the
truce. Al-Akhnas bin Shariq wrote to the Prophet (ﷺ) requesting him to return Abu Basir.
