Is it permissible for one who is observing i‘tikaafto leave the mosque in order to wake his familyup for sahoor, then come back?

If the person who is observing i'tikaaf comes out of his place of
i'tikaaf to wake his family up for sahoor, and that is because there
is no one athome, is this regarded as contrary to the conditionsof
i'tikaaf?.
Praise be to Allaah.
The one who enters i'tikaaf should not leave his place of i'tikaaf
during his i'tikaaf, except for necessary, unavoidable reasons and to
tend to hisneeds, such as bringing food and drink if there is no one
who can bring them for him, and relieving himself if there are no
washrooms in the mosque. There is nothing wrong with him going out at
the time of sahoor to wake his family up so that they can eat sahoor
at the proper time, and towake them up to pray Fajr if they cannot
wake up by themselves and there is no one else who can wake them up,
because that comes underthe heading of encouraging one another to do
good and enjoining them to do what is right. If an obligatory duty
cannot be done without athing, then that thing becomes obligatory. But
he should not sit at home after waking his family up; he should go
back to his place of i'tikaaf in the mosque.
And Allah is the source of strength. May Allah send blessings and
peace upon our Prophet Muhammad and his family and Companions. End
