Madina would have beenbetter for them, had they but known. Ash-Sham will be conquered andpeople will be attracted to it, taking their families and whoeverobeys them. Madina would have been better for them, had they butknown. Iraq will be conquered and people will be attracted to it,taking their families and whoever obeys them. Madina would have beenbetter for them, had they but known.' "
