والذين يتوفون منكم ويذرون أزواجا يتربصن بأنفسهن أربعة أشهر وعشرا فإذا بلغن أجلهن فلا جناح عليكم فيما فعلن في أنفسهن بالمعروف والله بما تعملون خبير
And those who pass away among you and leave behind wives, (the widows) should wait for themselves (for) four months and ten (days). Then when they reach their (specified) term, then (there is) no blame upon you for what they do concerning themselves in a fair manner. And Allah of what you do (is) All-Aware.
